使用 maven-antrun-plugin 进行 Groovy 编译时出现异常

Question

我有一堆 Groovy 文件，我需要将它们与 Java 类一起包含到一个 jar 文件中。一开始，我为 Groovy 编译创建了单独的 Maven xml 文件。结果是 Zip 异常。

Maven XML 脚本如下：

Answer 1

首先，Groovy JSR jar 中的编译类非常古老。我不建议将其用作定义 Groovyc 类的依赖项。这很可能是您的问题的原因。我不确定你想做什么。如果你想通过 JSR223 调用，编译没有意义。如果你正在编译，使用 JSR 依赖没有任何意义。

继续前进。这是一个完整的示例，包括使用最新 Groovy 版本的测试类路径：https://gist.github.com/keeganwitt/d56b4b81165a264061d5。如果您使用 Maven，我强烈建议您考虑 GMavenPlus（或者如果您愿意，也可以考虑使用 Groovy-Eclipse Compiler Plugin for Maven）。我做了一个比较，试图帮助人们在这里选择：http://docs.codehaus.org/display/GMAVENPLUS/Choosing+Your+Build+Tool。

编辑：我还更新了您可能从 (http://docs.codehaus.org/display/GROOVY/Compiling+With+Maven2) 获得的过时 wiki 页面。
