I have a multi-module project in my IntelliJ environment. I want to create and deploy war for only one module in apache tomcat. (IntelliJ comes with default installation of tomcat.)
I have worked almost four years with Eclipse and started with IntelliJ like three days back. Just the way we right click on the project in eclipse and say export as war and it directly deploys in my app server, can I do same / similar in IntelliJ?
Any help will be helpful.
Thanks
PS : may be stupid to ask but would mac / windows make difference?
This absolutely works!
First:
Wow, I was reading and trying the answers provided and i couldnt believe why no one mentions the root of the issue which is "NOT MENTIONING THE WAY YOU WANT YOUR OUTPUT TO BE" which is war so lets first tell intellij what we want by adding bellow tag to your pom.xml
<packaging>war</packaging>
where to paste? anywhere inside <project> tag
Now lets talk about the method
You can install "Maven Helper" plugin as it will help beginners nicely, but if your intelij has a good handshake with maven, it will automatically or manually refresh your project and add the war capability to your maven settings ( the panel you see at the right hand side of the editor that mentions Maven) there you click on Plugins and you should see now you have war (org.apache.maven.plugins:maven-war-plugin:xxx) as you click on the + you see many options, war:war and war:exploded are your friends to do what you like
<!-- Package as an executable jar/war -->
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
Use clean to dust off the previous mess, use war:war to create .war file, and for manifest war:exploded will do, if these didnt help for manifest, use the
File | Project Structure and click Artifacts.
Click Add + and 'Web Application:war exploded' then it will pop-up your project and select it and hit OK and then go and do Build > Build Artifact.
Good luck.
IntelliJ has different process to build war:
Goto -> Files -> Project Structure -> Artifacts
In artifacts tab, you will see a small + button on top right corner.
Click it and fill up the right panel data such as name and output directory.
Make sure to create the Manifest file. Keep default location for Manifest file.
After building manifest, click apply->Ok.
Now you can go to Build-> Build Artifact.
Your .war file will be ready in the output folder you specified above.
you can use maven build to create war file.
Go to right maven -> Lifecycle -> double click package. You can see your war generated default directory i.e Target
It took me a while to realise that you can't build a war file with intellij community edition, at least I could not do it looking at answers from this thread.
My approach was to download and activate "Maven Helper" plugin directly from the IDE ie. File->settings->Plugins.
Then, select your pom.xml in the project viewer and in the "Run" tab, you will be able to choose Run new Maven Goal.
There simply add the command line "clean install".
Your war file (if you selected war in your pom.xml file) will be located under the folder "target" in your project main folder.
File | Project Structure Ctrl+Shift+Alt+S and click Artifacts.
Click Add + and create a Web Application: Archive For 'Web Application:war exploded'
Build | Build Artifacts > Web Application: war > Build
You should see the artifact <project >/out/artifacts/Web Application_war.war

File | Project Structure Ctrl+Shift+Alt+S and click Artifacts.
Click Add + and select 'Web Application:war exploded' click 'From modunles..' and select Modules
Click Add + and select 'Web Application:war Archive' click 'Modules:war exploded'
Build | Build Artifacts > Web Application: war > Build
You should see the .war file in 'out/artifacts/'. And you can use it to deloy onto the Glassfish Server

In IntelliJ integrated with Tomcat maintaining a Maven project.
Occasionally the project structure changes and new JARs are being added and/or their versions keep changing, the changes are left out of the WEB-INF/lib.
In order to maintain a correct setup, I have to add them manually in the module structure to run Tomcat correctly. This happens a lot!
Can this be automated?
Manually adding missing JARs
EDIT:
After watching Eric Green's response I did some experimenting:
The project is a parent/child project with multiple poms in it's children.
After playing around with the pom.xml of the project and modifying the main <packaging>jar</packaging> to <packaging>war</packaging> I was able to make IntelliJ to automatically include everything it needs in WEB-INF/lib , I had to do more several modifications to fix the project but eventually this was the main issue. Otherwise I had to manually specify the needed dependencies in WEB-INF/lib.
Notice how the dropdown in the top toolbar in the image below has a Tomcat icon. This configuration automatically builds a standard web application, part of which of course being the placing of necessary dependencies into the WEB-INF/lib folder of the generated *.WAR archive (see the JARs inside WEB-INF/lib under the target directory in the image below). These were all placed there automatically by Maven during the "package" phase. See the steps at the bottom (below the screenshots) to ensure this occurs correctly.
Below is another screenshot showing the Run/Debug configuration for a Tomcat application. Maven is actually doing all the real work of assembling dependencies into a correct WAR archive, but IntelliJ is assisting in the management and deployment of the artifacts to the configured local Tomcat server.
So, to do this for yourself:
Set the packaging in your project's pom.xml file as "war"
Go to Run > Edit Configurations
Click the plus sign '+' and click Tomcat Server > Local
Fill in the dialog that pops up as directed
Run your Maven build ("clean install", or whatever you fancy)
Start Tomcat with your new Run/Debug configuration created in steps 3 and 4
I have a Maven based desktop App and I have to convert it to a dynamic web app in eclipse or any other IDE ( I am using Eclipse Neon-Java EE).
I have tried with Project Facets (Right click on project name --> Properties --> Project Facets --> dynamic web app) It generates some files but it doesn't seem to be converted to web as in the project folder still appears the letter "M" and not the golobe icon. When I try to run it in Tomcat it doesn't work.
Project Folder
Any suggestion?
Thank you
Look into the project if you have the Maven convert option...
If not, you should check the property of the project, and change them manually, starting from the Deployment Assembly, the target runtime, check all the facets..
Then take a look into the folder of the project, into .classpath and .project and see if they have been refreshed by Eclipse, the pom should package as a war and so on...
The problem here is that you are fighting with Maven and Eclipse togheter, so my main suggestion to do this in lees time, is to create a new Dynamic project and then to copy and paste all the previous Desktop project.. you can do this in a lot of ways...
Or directly from the IDE, or simply by hand than importing again the project...
Let me know if you try one of the above suggestions :)
Moreover obviously after all of this it won't start in tomcat, you have before to configure your web.xml and so on... but at least your structure will follow the Dynamic Web Project structure standards..
How do I import a jar in Eclipse?
You can add a jar in Eclipse by right-clicking on the Project → Build Path → Configure Build Path. Under Libraries tab, click Add Jars or Add External JARs and give the Jar. A quick demo here.
The above solution is obviously a "Quick" one. However, if you are working on a project where you need to commit files to the source control repository, I would recommend adding Jar files to a dedicated library folder within your source control repository and referencing few or all of them as mentioned above.
Adding external Jar is not smart in case you want to change the project location in filesystem.
The best way is to add the jar to build path so your project will compile if exported:
Create a folder called lib in your project folder.
copy to this folder all the jar files you need.
Refresh your project in eclipse.
Select all the jar files, then right click on one of them and select Build Path -> Add to Build Path
Two choices:
1/ From the project:
2/ If you have already other jar imported, from the directory "References Libraries":
Both will lead you to this screen where you can mange your libraries:
Here are the steps:
click File > Import. The Import window opens.
Under Select an import source, click J2EE > App Client JAR file.
Click Next.
In the Application Client file field, enter the location and name of the application client JAR file that you want to import. You can click the Browse button to select the JAR file from the file system.
In the Application Client project field, type a new project name or select an application client project from the drop-down list. If you type a new name in this field, the application client project will be created based on the version of the application client JAR file, and it will use the default location.
In the Target runtime drop-down list, select the application server that you want to target for your development. This selection affects the run time settings by modifying the class path entries for the project.
If you want to add the new module to an enterprise application project, select the Add project to an EAR check box and then select an existing enterprise application project from the list or create a new one by clicking New.
Note: If you type a new enterprise application project name, the enterprise application project will be created in the default location with the lowest compatible J2EE version based on the version of the project being created. If you want to specify a different version or a different location for the enterprise application, you must use the New Enterprise Application Project wizard.
Click Finish to import the application client JAR file.
Just a comment on importing jars into Eclipse (plug-in development) projects:
In case you are developing Eclipse plug-ins, it makes sense to use Eclipse's native bundling mechanism instead of just importing the jar into a plug-in project. Eclipse (or better its underlying OSGi runtime, Equinox) uses so-called bundles which contain some more information than plain jars (e.g., version infos, dependencies to other bundles, exported packages; see the MANIFEST.MF file). Because of this information, OSGi bundles can be dynamically loaded/unloaded and there is automatic dependency resolution available in an OSGi/Eclipse runtime. Hence, using OSGi bundles instead of plain jars (contained inside another OSGi bundle) has some advantages.
(BTW: Eclipse plug-ins are the same thing as OSGi bundles.)
There is a good chance that somebody already bundled a certain (3rd party) library as an OSGi bundle. You might want to take a look at the following bundle repositories:
http://www.springsource.com/repository/app/
http://download.eclipse.org/tools/orbit/downloads/
http://www.osgi.org/Repository/HomePage
Eclipse -> Preferences -> Java -> Build Path -> User Libraries -> New(Name it) -> Add external Jars
(I recommend dragging your new libraries into the eclipse folder before any of these steps to keep everything together, that way if you reinstall Eclipse or your OS you won't have to rwlink anything except the JDK) Now select the jar files you want. Click OK.
Right click on your project and choose Build Path -> Add Library
FYI just code and then right click and Source->Organize Imports
Jar File in the system path is:
C:\oraclexe\app\oracle\product\10.2.0\server\jdbc\lib\ojdbc14.jar
ojdbc14.jar(it's jar file)
To import jar file in your Eclipse IDE, follow the steps given below.
Right-click on your project
Select Build Path
Click on Configure Build Path
Click on Libraries, select Modulepath and select Add External JARs
Select the jar file from the required folder
Click and Apply and Ok
first of all you will go to your project what you are created
and next right click in your mouse and select properties in the bottom
and select build in path in the left corner and add external jar file add click apply .that's it
In eclipse I included a compressed jar file i.e. zip file. Eclipse allowed me to add this zip file as an external jar but when I tried to access the classes in the jar they weren't showing up.
After a lot of trial and error I found that using a zip format doesn't work. When I added a jar file then it worked for me.
Right Click on the Project.
Click on Build Path.
Click On Configure Build Path.
Under Libraries, Click on Add Jar or Add External Jar.
If you are having a trouble on udemy course of chad on springboot for the importing the jar. Then follow these steps.
Right click on the project.
You will see a option of Build Path, click on it.
You will have a option of Configure Build path, click on it.
Go to libraries.
Then go to the place where you have a jar files make them into a new folder and upload on a new place.
Then click on Add External Jars, you will surely be able to upload it which will help on classpathxmlapplicationcontext as well.
Thank you.
I am trying to import the latest Log4j2 source in my eclipse and Eclipse is not detecting it as a project. it says 'No projects are found to import'. Is there a solution for this?
My goal is to make a jar out of this source. Can i do that without the need to importing it on my eclipse(maybe like a command line solution that can make a build for me)?
Eclipse is not detecting it as a project. it says 'No projects are found to import'. Is there a solution for this?
It's a maven project, so you should import Existing Maven Project
Can i do that without the need to importing it on my eclipse(maybe like a command line solution that can make a build for me)?
A simple jar command. You can see more at Using JAR Files: The Basics. A basic command example
> jar cf log4j-sources.jar * // the * is for all files in the current directory
Note: this will not build anything. Just put everything into a jar.
If you have maven you can ask maven to generate the Eclipse .project and .classpath files.
From the log4j2 top-level folder, run mvn eclipse:eclipse
Eclipse will now be able to recognize each module as a project.
After this, to import modules in Eclipse, take the following steps for each module:
File > New > Java Project - enter module name (e.g. log4j-api) for Project name, uncheck "Use default location" and click Browse... to navigate to the location of the log4j-api module. Then click Finish on the wizard.
I am trying to export an existing Eclipse project to a war file. But whatever I typed in the "WAR Export" dialog page, the system always returned "Module name is invalid". I do not know how to fix this issue. Thanks for the help.
I had the same issue, and I fixed it. Please follow the steps below, and you can create your war file.
Right-click on folder project.
Click on properties.
Go to project facets.
Activate, if necessary.
Scroll down to Configuration and mark Dynamic Web Module.
This works for me.
you must be sure your project is a Web Project, if it's not a Web Project check this link: http://eclipse.dzone.com/tips/converting-java-project-dynami
In Eclipse STS
Right-click on folder project.
Click on properties.
Go to project facets.
Choose your Java 1.8
Scroll down to Configuration and mark Dynamic Web Module.
After that, it works fine.
In my case error went off when the war file name matched the project name of the eclipse. Its easy to choose one from the drop down box.
If your project is a Maven project. In Export Wizard, Module name combo box will be empty and any inputs will be invalid.
Solution: If you build the project using Maven. - In project / package view Open context menu on the project > Run > Maven Build
The WAR file will be packaged in target directory.
Note: PUM file of the project should be configured for packaging WAR file.
Right-click on folder project.
Click on properties.
Go to project facets.
Choose your Java 1.8
Scroll down to Configuration and mark Dynamic Web Module.
When I follow this step getting me the error (Dynamic Web Module 3.0 java 1.6 or newer)
I'm currently using Java 11
I am not sure about the exact cause. But this gets resolved most of the times if you give the exporting project war file name just same as the project name in the IDE
When I converted my java project onto dynamic web project using eclipse for EE developers, I encountered this.
Then I made a whole new dynamic web project and copied all my source files to it, and I was able to export a war file easily.
