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.

blocks|key|3010915|text|看一下项目中的.classpath文件，它可能包含您需要的大多数信息。最简单的选择可能是将您自己的"build.xml导出“，即在构建过程中将.classpath处理到一个新的build.xml中，然后使用ANT子任务调用它。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3010916|对我来说，解析一小段XML听起来要比挂接到Eclipse+JDT容易得多。|3010917|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

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.

blocks|key|3224797|text|我自己也一直在尝试做同样的事情。我发现"Export+Ant+Buildfile“是在org.eclipse.ant.internal.ui.datatransfer.AntBuildfileExportPage.java文件中启动的。它驻留在org.eclipse.ant.ui插件中。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3224798|要查看源代码，使用Plug-in+Development透视图并打开Plug-ins视图。然后右键单击org.eclipse.ant.ui插件并选择import+as+>+source+project。|3224799|我的计划是创建一个Java程序，以编程方式启动ant构建文件的生成，并在每次构建时在Ant文件中调用它，方法是将ant文件添加到项目的构建器中(在项目的builders选项卡下右键单击preferences+)。|3224800|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

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'm the one who donated the Ant export filter to Eclipse. I added the auto export feature, but only to my personal plug-in <a href="http://timealias.bplaced.net/eclipse2ant/" rel="nofollow">eclipse2ant</a>, which I still maintain to coordinate bug fixes.

Unfortunately I have no time to merge it to the official Eclipse builds.

If all you need is the classpath entries, I do something like the following to use the eclipse build path.

<pre><code>&lt;xmlproperty file=".classpath" collapseAttributes="true" delimiter=";" /&gt;
</code></pre>

Then set that value in the path

<pre><code>&lt;path id="eclipse.classpath"&gt;
 &lt;pathelement path="${classpath.classpathentry.path}"/&gt;
&lt;/path&gt;


&lt;target name="compile" depends="init"&gt;

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:

<a href="https://github.com/joaobispo/ant-build-for-java-eclipse/releases/download/v1.0/ant-build-for-java-eclipse.jar" rel="nofollow">ant-build-for-java</a>

To use it, call:

<pre><code>java -jar ant-build-for-java.jar &lt;folder with repositories&gt; [&lt;.userlibraries file&gt;]
</code></pre>

The first argument is the folder with the repositories. It will search the folder recursively for any <code>.project</code> file. The tool will create a <code>build.xml</code> 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.

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!
