具有顺序ant-contrib的Maven antrun无法运行

Question

我们有一个特殊的例程来将子文件夹中的文件分解为扩展,这些扩展将被复制并放入单个扩展文件中.对于这种特殊的方法,我想使用maven-antrun-plugin,通过dirset的顺序迭代和jar包装,我们需要库ant-contrib.

即将推出的插件配置失败并显示错误.我错误配置了什么？谢谢.

Answer 1

因此我浪费了至少一个小时的时间才能找到错误的一点提示......

我使用maven3和其余如上所述,但我必须使用maven.dependency.classpath 而不是maven.plugin.classpath!否则maven将找不到contrib任务.希望这可以帮助任何人.

Answer 2

看起来你错过了声明ant-contrib任务所需的taskdef,因此Ant知道它们,因此这部分错误消息:

Problem: failed to create task or type for

(如果失败的任务'for'- 被引用可能会更清楚一些.)

添加taskdef的一种方法是在for循环之前立即插入:

<target>
    <taskdef resource="net/sf/antcontrib/antlib.xml"
             classpathref="maven.plugin.classpath" />
    <for param="extension">
    ...
