Ant2IDE<\/em> generates Eclipse (or other IDE<\/span>-specific) project files with proper classpath and source folder settings from Ant build.xml<\/code> automatically.<\/p>\n\n\n\n

I wrote ant2eclipse<\/a> long time ago with my crude shell script skill to generate Eclipse project files from an Ant build.xml<\/code> file.<\/p>\n\n\n\n

In Ant2IDE, I extended the idea so that it works in a more elegant way using the BuildListener<\/a> interface. The usage is pretty simple:<\/p>\n\n\n\n

    \n
  1. Add ant2ide.jar<\/a> to the classpath:
    export CLASSPATH=\"\/usr\/local\/libexec\/ant2ide.jar:$CLASSPATH\"<\/pre><\/li>\n\n\n\n
  2. Change the working directory to the project home:
    cd \/home\/trustin\/workspace\/myAntProject<\/pre><\/li>\n\n\n\n
  3. Clean the build
    ant clean<\/pre><\/li>\n\n\n\n
  4. Run ant<\/code> with the -listener<\/code> option and appropriate task(s):
    ant -listener net.gleamynode.ant2ide.EclipseProjectGenerator compiile-main compile-test<\/pre><\/li>\n<\/ol>\n\n\n\n

    You might prefer to use the following simple shell script:<\/p>\n\n\n\n

    #!\/bin\/sh\n# Path: \/usr\/local\/bin\/ant2eclipse\nexport CLASSPATH=\"$CLASSPATH:\/usr\/local\/libexec\/ant2ide\/ant2ide.jar\"\nant -listener net.gleamynode.ant2ide.EclipseProjectGenerator \"$@\"<\/code><\/pre>\n\n\n\n

    How it works<\/h3>\n\n\n\n

    How does Ant2IDE generate the Eclipse project files? It listens to the build events fired by Ant and records the source and destination directory of the javac<\/code> tasks into its internal data structure. Once build is completed successfully, Ant2IDE processes the recorded information to generate IDE<\/span>-specific project files. It\u2019s very simple but it works much better than analyzing build.xml<\/code> directly or creating a new Java project from an Eclipse workbench.<\/p>\n\n\n\n

    Caveats<\/h3>\n\n\n\n

    Of course, Ant2IDE is not a silver bullet \u2013 there\u2019s some limitation in this approach.<\/p>\n\n\n\n

    First, you can\u2019t get the correct build information unless you provide a proper Ant target. For example, clean<\/code> target will never help AntIDE generate the project files. You should specify the target that compiles all source code, such as build-all<\/code> or all, test-all<\/code>.<\/p>\n\n\n\n

    Second, it doesn\u2019t add all resource directories automatically. You have to add them manually for most cases. There\u2019s no way to determine exactly whether a copy<\/code> task copies resource files for now. One exception is when your project has a directory layout which is similar to that of Maven<\/a> 2 project; Ant2IDE looks for a resources<\/code> directory when the name of the source code directory is java<\/code>, and add the resources directory to the source path automatically.<\/p>\n\n\n\n

    Third, Eclipse JDT<\/span> is the only IDE<\/span> that Ant2IDE supports at this moment. It\u2019s designed to support other IDE<\/span>s such as NetBeans and IntelliJ, but I don\u2019t use them these days. Any contribution would be great.<\/p>\n\n\n\n
