使用maven- anrun -plugin进行Groovy编译时的异常

Question

我有一堆Groovy文件，我需要将它们与Java类一起包含到jar文件中。开始时，我创建了单独的Maven xml文件，仅用于Groovy编译。结果是Zip Exception。

Maven XML脚本如下:

                            </taskdef>
                            <mkdir dir="${basedir}/target/WEB-INF/classes"/>
                            <groovyc destdir="${basedir}/target/WEB-INF/classes"

                            </groovyc>
                        </tasks>
                    </configuration>
                    <goals>
                        <goal>run</goal>

                </execution>

首先，Groovy JSR jar中的编译类非常古老。我不建议使用它作为您定义Groovyc类的依赖项。这很可能是你的问题的原因。我不知道你到底想干什么。如果您想通过JSR223调用，那么编译就没有意义了。如果你正在编译，使用JSR依赖没有意义。

。下面是一个完整的示例，包括使用最新Groovy版本的测试类路径:https://gist.github.com/keeganwitt/d56b4b81165a264061d5。如果您正在使用Maven，我强烈建议您考虑使用GMavenPlus(如果您愿意，也可以使用Maven的Groovy-Eclipse编译器插件)。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:我也更新了过时的wiki页面，你可能从(http://docs.codehaus.org/display/GROOVY/Compiling+With+Maven2)得到这个。
