如何使用ant4eclipse复制所有引用的eclipse项目的jar包？

我试过像这样（link）：如何使用ant4eclipse复制所有引用的eclipse项目的jar包？

<taskdef resource="net/sf/antcontrib/antlib.xml" /> 
<taskdef resource="net/sf/ant4eclipse/antlib.xml" /> 

<target name="copy_jars"> 
    <getEclipseClasspath workspace="${basedir}/.." 
         projectname="MyProject" 
         property="classpath" 
         relative="false" 
         runtime="true" 
         pathseparator="#" /> 

    <!-- iterate over all classpath entries --> 
    <foreach list="${classpath}" delimiter="#" 
    target="copy_jar_file" param="classpath.entry" /> 
</target> 

<target name="copy_jar_file"> 
    <!-- check if current is a .jar-file ... --> 
    <if> 
    <isfileselected file="${classpath.entry}"> 
     <filename name="**/*.jar" /> 
    </isfileselected> 
    <then> 
     <!-- copy the jar file to a destination directory --> 
     <copy file="${classpath.entry}" tofile="${dest.dir}"/> 
    </then> 
    </if> 
</target>

但我得到异常：

我wan't只复制的罐子，而不是被引用的项目。有没有办法参数化任务getEclipseClasspath，所以它只获取罐子，而不是项目？

我在重新输入错误时犯了一个错误：无法解析插件项目'E：\ ... \ MyReferencedProject'，因为它既不包含Bundle-Manifest也不包含plugin.xml！我试图从“MyProject”类路径中删除MyReferencedProject，然后复制所有罐子并正常工作。有没有人知道为什么它把“MyReferencedProject”作为一个插件项目？不是。 – davorp 2009-10-22 11:04:52

MyReferencedProject的类路径条目看起来像这样：虽然一个罐子类路径条目看起来像：我想过滤classpath条目，只需要那些kind =”lib“。 – davorp 2009-10-22 11:10:14

验证： 1.为项目名称的getEclipseClasspath属性，其实，“MyProject的” 2.“MyProject的”实际上是一个Java项目，在构建路径中定义的条目 3.已添加Ant-> Runtime-> Classpath（tab） - > Ant Home Entry - >“Add jars”（button）

如果Ant4Eclipse和AntContrib仅从您的ant脚本引用，那么您引用的示例代码将不起作用 - 这些jar必须添加到Eclipse配置中的Ant运行时类路径中。
