I'd like to set up an Ant build that pulls down its plugins at buildtime. So for instance, if my build used findbugs and checkstyle JARs and called their tasks from inside build.xml, then ideally I could:

  1. Run an ivy-resolve and ivy-retrieve task to pull findbugs and checkstyle JARs down into, say, gen/lib/buildtime.
  2. Add gen/lib/buildtime to Ant's classpath
  3. Define <taskdefs> that define the various findbugs and checkstyle tasks
  4. Execute the findbugs and checkstyle tasks in a downstream target

Is this possible? If so, how? I think the only show-stopper here is the fact that I don't think you can dynamically add <taskdefs>... thanks in advance!

最好的方法是使用cachepath任务来使用所需的 jar 填充 ANT 路径。你的 taskdef 然后变成：

<ivy:cachepath pathid="build.path" conf="build"/>
<taskdef uri="antlib:org???" resource="???" classpathref="build.path"/>

常春藤配置可用于控制应填充路径的 jar。

以下示例使用Sonar自动运行 findbugs 和 checkstyle。它演示了使用 ivy 引入以下 ANT 插件：

  • 朱尼特
  • 声纳
  • 雅可可
