我正在使用IBM的Rational Application Developer。我有一个包含Java2WSDL任务的ant脚本。当我通过IBM运行它时，它会产生编译错误，除非我通过运行工具在类路径中包含j2ee.jar文件（它不会在脚本的类路径中获取jar文件）。但是，我需要能够以编程方式调用此脚本，并且它给了我这个错误：“java.lang.NoClassDefFoundError：org.eclipse.core.runtime.CoreException”我不确定需要添加哪个jar或者哪里？由于运行一个简单的echo脚本，我认为它是j2ee.jar或需要添加的另一个ant jar。我已将它添加到项目的构建路径中，但这没有用。 （我还有ant.jar，wsanttasks.jar，插件中的所有ant jar，tools.jar，remoteAnt.jar和swt - 当你自己运行脚本时，所有这些都包含在buildpath中。）
脚本：
<?xml version="1.0" encoding="UTF-8"?>
<project default="build" basedir=".">
<path id="lib.path">
<fileset dir="C:\Program Files\IBM\WebSphere\AppServer\lib" includes="*.jar"/>

Adding these does not help.

代码：
File buildFile = new File("build.xml");
Project p = new Project();
p.setUserProperty("ant.file", buildFile.getAbsolutePath());
DefaultLogger consoleLogger = new DefaultLogger();
consoleLogger.setErrorPrintStream(System.err);
consoleLogger.setOutputPrintStream(System.out);
consoleLogger.setMessageOutputLevel(Project.MSG_INFO);
p.addBuildListener(consoleLogger);
try {
p.fireBuildStarted();
p.init();
ProjectHelper helper = ProjectHelper.getProjectHelper();
p.addReference("ant.projectHelper", helper);
helper.parse(p, buildFile);
p.executeTarget(p.getDefaultTarget());
p.fireBuildFinished(null);
} catch (BuildException e) {
p.fireBuildFinished(e);
}
