What is the file build.xml?
I was wondering if it is a possibility to import this project in Eclipse or Netbeans using this build.xml. I tried to import the project but I get some errors since one part is created using J2ME and the other J2SE and I guess this file should be the configuration.
build.xml usually is an ant build script.
It contains information necessary to build the project to produce the desired output, be it Javadocs, a compiled project, or a JAR file.
I believe Eclipse has ant built-in, so it should be possible to execute the build.xml by choosing "Run As..." and "Ant Build".
The build.xml file, if it is an ant script, is not used to import the project into an IDE like Eclipse or Netbeans. A build script is used to build the project (or produce some desired output) rather than an mechanism for importing the project into an IDE.
As mentioned by #coobird this is an ant build file. Although IDEs such as Eclipse and Netbeans have ant support built-in, it is also possible to run ant from the command-line and this may be the simplest way to get started if the project has been well created.
See http://ant.apache.org/
for docs.
If you want to try this approach, install ant, cd to the directory with build.xml and issue
ant
Eclipse can be told to build using an Ant script, but you can also use Ant itself.
build.xml file is an Ant(Apache) script.
you can find more information on Ant & build.xml here
In java project build.xml file is used write the ant script.
And from that ant script you can generate war file and can deploy on Tomcat server

I have completed my JavaFX application within gradle build system, and it is working fine in all way. Now I want to export as a .EXE file for standalone software distribution, I tried much more tricks but no gain. If some one can help me out to wrap my project in a software setup, It would be grateful.
Follow these steps to export your JavaFX project into executable Jar
Goto> Project Structure
Goto>>Artifacts
Click "+">> To add new artifact
It will shows a dropdownlist
Select>>Jar>>From module with dependencies
You will see a nested window as shown
Select Main class of your project
Check In the Option " Copy to output directory.." >>Ok
Goto>> Menu-bar>>Build>>Build Artifacts
Select>> your Project.jar>> Build
This will create executable jar file in your project source folder
Locate your jar file in path project\out\artifacts..
Now you can run this jar file simple cmd commad or with batch file
Cmd Command>> Java -jar project.jar
Using batch file>> make .bat file name it "RUN" and write these commands inside
Specify the Java Runtime path and "Javafx Sdk path" along with VM
options & Project Jar
Run your standalone application .. Enjoy ;)
Creating an installer for the desktop platforms (Windows, macOS, Linux) has become easy these days. The tool of choice is jpackage which started to be shipped with JDK 14. It can either be used on the command line on the finished project or you can use a Gradle plugin (https://github.com/beryx/badass-jlink-plugin). If your project is not modularized you could follow this tutorial https://github.com/dlemmermann/JPackageScriptFX which also uses jpackage but together with Maven and some other tools from the JDK. The Maven part could easily be rewritten to Gradle, if needed.
I have setup intellij to build a working jar file for the project. However, I need to be able to see what command is being used to generate this, so I can build it directly from the command line.
Any ideas?
Many thanks,
Sam
You may try to use Build -> Generate Ant Build from menu. It will create an ant file that will build the project.
I have a NetBeans project I would like to compile from the command line. There are many other questions on StackOverflow about how to do so, but they explain how to compile the project using commands like javac src/*.java.
I haven't changed my NetBeans project's build settings. By default, how can I compile my project from the command line using Ant? Once I've built my project, where is the compiled file located, and what format is it in (i.e., .class files, one .jar file, etc.)?
(I understand that asking how to use Ant to compile my project in general is too broad of a question. That's why I'm specifically asking about how to compile using NetBean's default configuration for a project.)
I'm using NetBeans 8.0.2.
ant compile Compiles the project (.class files are placed in the build/classes folder)
ant jar Compiles the project (see above) and builds a JAR ( located in dist/ )
If that doesn't work for you, check ant's output for errors. (Is the JAVA_HOME Variable set properly?)
I'm totally agnostic IDE developer. After several frustrating years trying to emerge "netbeans ant config" to something usable from command line I became to create a wrapper for netbeans ant.
https://github.com/albfan/ant-netbeans
By now you can:
detect defined targets with standard
$ ant tabtab
Rely on project will honor JDK_HOME
and most important
Expect all ant target to complete smoothly, passing test and whatever stuff implied.
So I have this Java project made up of several classes, some external JAR files and an executable Java program. I would like to export the whole code and external JARS to an external directory and to produce a Makefile to build the program with all the dependencies. Is there an automated way to do it?
Thank you

I think I understand the question. Of course if you use an external build system like maven or ant, then we are decoupling the build process from the IDE. (But in some cases the IDE does integrate pretty closely with the build tool.)
But if you want to continue building using eclipse and to generate an ant file one fine day, then there is a tool for that. Its called EBuild. It leverages all the classpath information that eclipse already has and builds an generic ant file out of it.
Do you use maven?
If so this can be easily achieved with maven assembly.
If not, you can use ant to bundle exactly what you need.
When you right-click your project in Eclipse, there is an option called "Export". It can create build.xml for ant for your project.
From Eclipse, I found I can easily export an Ant build file for my project. It provides references to 3rd party libraries and some base targets. I'm using it from my global build file. The only thing that bothers me about this, is that if something is modified in the project structure (like adding a new 3rd party library), we have to think (yes that can be hard sometimes!) about regenerating that build.xml file. I'm wondering if anyone here knows a way to have it updated automatically. By "automatically" I mean that it would not be necessary to explicitly ask Eclipse to regenerate it every time it's needed. I don't know what could be the trigger though...
Any thoughts or knowledge on this?
Thanks!

Right-click on an Eclipse project then "Export" then "General" then "Ant build files". I don't think it is possible to customise the output format though.
I have been trying to do the same myself. What I found was that the "Export Ant Buildfile" gets kicked off in the org.eclipse.ant.internal.ui.datatransfer.AntBuildfileExportPage.java file. This resides in the org.eclipse.ant.ui plugin.
To view the source, use the Plug-in Development perspective and open the Plug-ins view. Then right-click on the org.eclipse.ant.ui plugin and select import as > source project.
My plan is to create a Java program to programmatically kick off the ant buildfile generation and call this in an Ant file every time I build by adding the ant file to the builders of my projects (Right-click preferences on a projet, under the builders tab).
I've had the same problem, our work environment is based on Eclipse Java projects, and we needed to build automatically an ANT file so that we could use a continuous integration server (Jenkins, in our case).
We rolled out our own Eclipse Java to Ant tool, which is now available on GitHub:
ant-build-for-java
To use it, call:
java -jar ant-build-for-java.jar <folder with repositories> [<.userlibraries file>]
The first argument is the folder with the repositories. It will search the folder recursively for any .project file. The tool will create a build.xml in the given folder.
Optionally, the second argument can be an exported .userlibraries file, from Eclipse, needed when any of the projects use Eclipse user libraries. The tool was tested only with user libraries using relative paths, it's how we use them in our repo. This implies that JARs and other archives needed by projects are inside an Eclipse project, and referenced from there.
The tool only supports dependencies from other Eclipse projects and from Eclipse user libraries.
Take a look at the .classpath file in your project, which probably contains most of the information that you want. The easiest option may be to roll your own "build.xml export", i.e. process .classpath into a new build.xml during the build itself, and then call it with an ant subtask.
Parsing a little XML sounds much easier to me than to hook into Eclipse JDT.
If all you need is the classpath entries, I do something like the following to use the eclipse build path.
<xmlproperty file=".classpath" collapseAttributes="true" delimiter=";" />
Then set that value in the path
<path id="eclipse.classpath">
<pathelement path="${classpath.classpathentry.path}"/>
</path>
<target name="compile" depends="init">
<javac srcdir="${src}" destdir="${build}" updatedProperty="compiled">
<classpath refid="eclipse.classpath"/>
</javac>
</target>
I'm the one who donated the Ant export filter to Eclipse. I added the auto export feature, but only to my personal plug-in eclipse2ant, which I still maintain to coordinate bug fixes.
Unfortunately I have no time to merge it to the official Eclipse builds.
Select File > Export from main menu (or right click on the project name and select Export > Export…).
In the Export dialog, select General > Ant Buildfiles as follows:
Click Next. In the Generate Ant Buildfilesscreen:
Check the project in list.
Uncheck the option "Create target to compile project using Eclipse compiler" - because we want to create a build file which is independent of Eclipse.
Leave the Name for Ant buildfile as default: build.xml
Click Finish, Eclipse will generate the build.xml file under project’s directory as follows:
Double click on the build.xml file to open its content in Ant editor:
