Spring boot dev tools not working in Net beans - java

I have read about spring boot dev tools and want to try it, I add the following to my pom
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
<optional>true</optional>
</dependency>
And turn on devtools restart manual trigger in Net beans options.
To run i use the following option org.springframework.boot:spring-boot-maven-plugin:1.3.2.RELEASE:run in Run Project-> Execute Goals
But when i change smth in code , project isn't rerun. What did i miss?

Click under the project Properties -> Build -> Compile is a checkbox "Compile On Save" which is ticked. Verified that this actually works by modifying .java file and checking the timestamps in the /target/classes.
Also by changing Execute goals in Run project Action in Netbeans project properties to the following:
process-classes org.codehaus.mojo:exec-maven-plugin:1.2.1:exec
Configuring explicit resource directory location (in my case src/main/resources) to pom.xml resolves the problem of not reloading:
<build>
...
<resources>
<resource>
<directory> src/main/resources </directory>
</resource>
</resources>
...
</build>

Spring boot profile based WAR using maven

I need to create WAR file based on specific environment properties file.
So I have created 2 properties files,
application.DEV.properties
application.PROD.properties
Now when I run the project using eclipse embedded tomcat, I pass on the -Dspring.profiles.active=DEV as VM argument. Then when I hit my endpoint, I can see the DEV related messages returned. Same is the case when I pass PROD as parameter.
Now, what I want to do is I want to create a WAR file with maven command and pass the parameter in such a way that my specific properties file gets loaded. So I have referred google as well as stackoverflow and found various options like below,
mvn clean install -Drun.profiles=DEV
mvn clean install -Drun.jvmArguments="-Dspring.profiles.active=DEV"
mvn clean install -Dspring.profiles.active="DEV"
mvn clean install -Dspring.profiles.active=DEV
I tried all above. When I hit the command, the WAR gets generated. but it doesn't get deployed on tomcat, because it cant read the properties file and gives error. It seems like the profile specific properties file does not get loaded in the WAR.
I want to know what is the alternative to -Dspring.profiles.active=DEV when I want to generate a WAR file using maven?
How to generate WAR to correctly include proper profile specific properties file?
I am using spring boot 1.5.14.RELEASE.
As commented on this answer by Mickael, you can get help from the maven documentation on how to use profiles : https://maven.apache.org/guides/introduction/introduction-to-profiles.html
The usual way to choose a profile with maven is
mvn -Pprod package
Where prod is the name of your profile. If you want to build with the dev profile, it would be
mvn -Pdev package
Such profiles are defined in your file pom.xml under project>profiles>profile. And at that place, you can specify packaging options.
Here is such a profile:
<profile>
<id>dev</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-undertow</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
<optional>true</optional>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<configuration>
</configuration>
</plugin>
</plugins>
</build>
<properties>
<!-- log configuration -->
<logback.loglevel>DEBUG</logback.loglevel>
<!-- default Spring profiles -->
<spring.profiles.active>dev${profile.no-liquibase}</spring.profiles.active>
</properties>
</profile>
You have to pass spring.profiles.active to the runtime, not to the "build runtime". The only spring profiles, which are desirable at build time, would be for testing purposes.
In case of "war on Tomcat", you can set spring.profiles.active:
(Globally) Create a file in <tomcat_home>/bin/ named setnev.sh (respectively .bat, when you are on a Windows machine) with:
export JAVA_OPTS="-Dspring.profiles.active=PROFILE_OF_THIS_TOMCAT"
respectively:
set JAVA_OPTS="-Dspring.profiles.active=PROFILE_OF_THIS_TOMCAT"
(Globally) Add a line to <tomcat_home>/conf/catalina.properties:
spring.profiles.active=PROFILE_OF_THIS_TOMCAT
(At Container level) Add a file named context.xml at $CATALINA_BASE/conf/[enginename]/[hostname]/ (, you could also put it into /<webapp_root>/META-INF/, but then you'd have to distinguish at build time) with the following content:
<Context>
<Environment name="spring.profiles.active" value="PROFILE_OF_THIS_TOMCAT" />
</Context>

Maven Tomcat7 run a dependency war

I have a question regarding maven and its tomcat7 plugin :)
I have the following maven projects:
plugin1: plain java project packaged as jar
plugin2: plain java project packaged as jar
webapp: standalone webapp project packaged as jar
those three project are properly build in maven and the outcome works fine:
I can use the jars from plugin1/plugin2
I can deploy the webapp war file to a web container
I can run tomcat7:run to start the webapp
Now, I need to provide different packaging of the webapp containing specific plugin setup.
i.e. I want to generate a war file with webapp + plugin1 and another one with webapp + pugin2
To achieve this, I have created 2 additionnal maven projects that declare dependancies on the webapp project + the appropriate plugin projects and are packaged as wars.
The generated war files have the expected content, and can be deployed to a tomcat, but when I try to use the maven tomcat plugin (tomcat7:run again), it simply doesnt start anything.
Though this is not blocking for me (my main point was to generate the war files), I have the feeling that I missed something.
the pom.xml for those aggregate projects looks like this (note that there is absolutly no code in those projects, these were just created for packaging with specific dependancies convenience).
<groupId>my.project</groupId>
<artifactId>live1</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>war</packaging>
<name>MyWebapp</name>
<properties>
<failOnMissingWebXml>false</failOnMissingWebXml>
</properties>
<dependencies>
<dependency>
<groupId>my.project</groupId>
<artifactId>plugin1</artifactId>
<version>${project.version}</version>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>my.project</groupId>
<artifactId>webapp</artifactId>
<version>${project.version}</version>
<type>war</type>
<scope>runtime</scope>
</dependency>
</dependencies>
<build>
<finalName>MyWebapp</finalName>
<plugins>
<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<version>2.0</version>
<configuration>
<url>http://localhost:8080/manager</url>
<server>localhost</server>
<path>/${project.build.finalName}</path>
</configuration>
</plugin>
</plugins>
</build>
Thanks !
note: long time lurker, first time asker here, if some information is missing tell me :)
Depending on the structure of your project it may not be suficient to just add a dependency of type war. You may need also to configure <overlays> as described here maven-war-plugin.
It looks like your final war does not provide the full web configuration that you expect. With overlays you can configure how the resources from the dependency will be packed into your final web app.
There must be some difference in the way that your external tomcat starts the app compared to the tomcat7 plugin. May be you can try -X option :
mvn -X tomcat7:run
This should log out some details, of what the embedded tomcat is configuring..

maven eclipse:eclipse order of source folders get lost

Iin Eclipse it's possible to change the order via project settings (Context menu -> Project settings). Tab Build Path, there you can move folders up/down. Following this steps changes the order of source folders.
But after a mvn eclipse:clean -> mvn eclipse:eclipse, the changes get lost. Is there a solution to do that permanently?
I have also done my changes in my POM without success:
<resources>
<resource>
<directory>${basedir}/src/main/java</directory>
</resource>
<resource>
<directory>${basedir}/src/main/resources</directory>
</resource>
</resources>
<testSourceDirectory>${basedir}/src/test/java</testSourceDirectory>
Many thanks for your help.
There is an M2Eclipse - Eclipse Maven Integration. Use it to utilize powers of both Maven and Eclipse.
Maven can automatically manage your projects dependencies. For example Gson library can be added to your project by inserting this to pom.xml:
<dependencies>
<dependency>
<groupId>com.google.code.gson</groupId>
<artifactId>gson</artifactId>
<version>2.3.1</version>
</dependency>
</dependencies>
if you have M2Eclipse in installed in your eclipse. New item Maven Dependencies will appear in Package Explorer under your project. And Gson library will be added to your classpaths.
You do not need to change dependencies order. They will be resolved by maven automatically.
Dependency management is one of Maven's main features. Use it.

how to deploy Spring MVC project on openshift.com

I wanted to Deploy a simple Spring MVC APP to open shift I googled for this and found spring-mvc-3-on-jboss but there project structure is different I have basic Spring MVC project structure is
that is at this repo, at openshift.com I created Application and configured as :
But I can not see my home.jsp file as welcome file when I goto my app-url I see only the default/traditional welcome page. Any suggestion how to configure project to work correctly?
There is one major problem with your pom.xml, I think that makes your app not working on the openshift.com. You should add the following lines to your pom.xml
<profiles>
<profile>
<!-- When built in OpenShift the 'openshift' profile will be used when
invoking mvn. -->
<!-- Use this profile for any OpenShift specific customization your app
will need. -->
<!-- By default that is to put the resulting archive into the 'webapps'
folder. -->
<!-- http://maven.apache.org/guides/mini/guide-building-for-different-environments.html -->
<id>openshift</id>
<build>
<finalName>yourAppName</finalName>
<plugins>
<plugin>
<artifactId>maven-war-plugin</artifactId>
<version>2.1.1</version>
<configuration>
<outputDirectory>webapps</outputDirectory>
<warName>ROOT</warName>
</configuration>
</plugin>
</plugins>
</build>
</profile>
</profiles>
I haven't tested this code with JBoss Application Server, so change your server to Apache Tomcat 7. that worked for me correctly.
first you have clone your git repository then automatically created folder in document folder.
then your war file extract and past your clone directory into webapps folder
and create test folder paste your code in folder and also root war file.
then your ulr in your folder name write and enter.
for example
like this.
git clone ssh://5565c850e0b8cd07580001ba#yourdomain.rhcloud.com
paste your extract war file into your clone directory.
then fire git commmand
$ git add .
$ git commit -m "A checkin to my application"
$ git push

Customised maven deployable (war with some dependencies removed)

I have a multi module web app building with maven. We build the war as per normal and deploy and run on developer machines and local test servers using tomcat.
Then we want to deploy the application to the cloud. To do this we create a special version of tomcat which has all the libraries preloaded and a special version of the war which only has our code. Point here is tomcat is preloaded on the cloud server, the war is uploaded each time it is changed. Currently we are having to manually remove the dependencies from the built war.
What is the best way for maven to do this? Should I build a custom packaging type or maybe run some post build plugin to remove these wars? Or something else? I think the best way to activate this custom build is via a profile. I did try and remove these dependencies by setting them to scope = provided in the new profile but the transitive dependencies still made it into the war.
If you want to exclude all dependencies, you can use the war plugin's packagingExcludes to do so:
<plugin>
<artifactId>maven-war-plugin</artifactId>
<version>2.2</version>
<configuration>
<packagingExcludes>WEB-INF/lib/*.jar</packagingExcludes>
...
</configuration>
</plugin>
Specify this plugin inside a profile to only perform it for production.
You can achieve using profile in maven. As you said it is not working, I can think of you configure something wrong. Try something like:
<profiles>
<profile>
<id>dev</id>
<activation>
<!-- active by default, turn off when on prod -->
<activeByDefault>true</activeByDefault>
</activation>
<dependencies>
<!-- include this in dev, not in prod -->
<dependency>
<groupId>com.company</groupId>
<artifactId>xyz</artifactId>
</dependency>
</dependencies>
</profile>
</profiles>
Then in command line, mvn package -P !dev to deactivate dev profile so that not include the jars.
Make sure com.company:xzy is not included in <project><dependencies></dependencies></project>.
