加入蚂蚁动态插件在生成时？ [英] Add ant plugins dynamically at buildtime?

问题描述

我想建立一个Ant构建，在构建时拉低它的插件。因此，举例来说，如果用我的构建 FindBugs的和的Checkstyle JAR文件，并呼吁他们的任务从内build.xml文件，那么最好我可以：

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. 运行的常春藤解析和常春藤提取任务拉 FindBugs的和的Checkstyle JAR文件分解成，比方说，根/ lib中/编译期。


2. 添加根/ lib中/编译期来Ant的类路径


3. 定义＆LT;任务定义＆GT; 定义各种 FindBugs的和的Checkstyle 任务


4. 在下游目标执行 FindBugs的和的Checkstyle 任务

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

这可能吗？如果是这样，怎么样？我觉得这里的唯一表明，塞的是，我不认为你可以动态地添加＆LT的事实;任务定义＆GT;！提前 ...谢谢

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!

推荐答案

最好的办法是使用的 cachepath 任务来填充需要的jar的ANT路径。然后，您的taskdef变为：

The best approach is to use the cachepath task to populate an ANT path with the required jars. Your taskdef then becomes:

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

这是常春藤配置可以用来控制罐子应该填充路径

An ivy configuration can be used to control which jars should populate the path.

下面的示例使用声纳自动运行的FindBugs和Checkstyle的。它演示了如何使用常春藤在以下ANT插件拉：

The following example uses Sonar to run findbugs and checkstyle automatically. It demonstrates using ivy to pull in the following ANT plugins:
