如何获得按住flattenmapper结果蚂蚁？ [英] How to get hold on the flattenmapper result in ant?

问题描述

请，看看下面几个目标从我的Ant文件：

Please, find below a few targets from my ant file:

<fileset id="test-dep-jars" dir="o:/java">
    <include name="junit-4.10.jar"/>
    <include name="easymock-3.1\easymock-3.1.jar"/>
    <include name="easymockclassextension-3.1\easymockclassextension-3.1.jar"/>
</fileset>

<target name="copy-test-deps">
    <mkdir dir="${deploy.dir}"/>
    <copy todir="${deploy.dir}">
        <fileset refid="test-dep-jars"/>
        <flattenmapper/>
    </copy>
</target>

<target name="jar" depends="copy-test-deps">
    <jar destfile="${deploy.dir}/test-${ant.project.name}.jar" basedir="${test.classes.dir}" 
         includes="**/*.class" filesetmanifest="skip">
        <manifest>
            <attribute name="Class-Path"
                       value="${ant.project.name}.jar junit-4.10.jar easymock-3.1.jar easymockclassextension-3.1.jar"/>
        </manifest>
    </jar>
</target>

我的问题是，我必须说明测试的依赖罐子两次 - 定义测试-DEP-jar文件时，文件集一次，并指定生产罐子的类Path清单属性当第二时间

My problem is that I have to state the test dependency jars twice - once when defining the test-dep-jars fileset and the second time when specifying the Class-Path manifest attribute of the produced jar.

如果我只能得到按住flattenmapper结果，那么我就可以使用它在类路径不变。

If I only could get hold on the flattenmapper result, then I would be able to use it in the Class-Path as is.

我怎样才能按住flattenmapper结果？

推荐答案

我会建议使用的 manifestclasspath 任务，而不是：

I would recommend using the manifestclasspath task instead:

<manifestclasspath property="jar.classpath" jarfile="${jar.file}">
    <classpath>
        <fileset dir="${deploy.dir}" includes="*.jar"/>
    </classpath>
</manifestclasspath>

<jar destfile="${jar.file}" basedir="${classes.dir}">
    <manifest>
        <attribute name="Main-Class" value="${jar.main.class}" />
        <attribute name="Class-Path" value="${jar.classpath}" />
    </manifest>
</jar>

这将产生正确的类路径属性定义，甚至与相对路径的工作（例如，如果你要放在子目录依赖罐）。

It will generate the correct classpath property definition and even works with relative paths (for example if you were to place the dependent jars in sub-directory).
