Question

可以使用Grape从Maven central下载依赖项：

@Grab(group='org.apache.commons', module='commons-lang3', version='3.4')

在type注释中指定jar Grab会做同样的事情：

@Grab(group='org.apache.commons', module='commons-lang3', version='3.4', type='jar')

根据javadoc，type的值也可以是javadoc和sources，但是在IntelliJ中尝试以下内容：

@Grab(group='org.apache.commons', module='commons-lang3', version='3.4', type = 'sources')

结果：

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
General error during conversion: Error grabbing Grapes -- [download failed: org.apache.commons#commons-lang3;3.4!commons-lang3.sources]

java.lang.RuntimeException: Error grabbing Grapes -- [download failed: org.apache.commons#commons-lang3;3.4!commons-lang3.sources]

Eclipse提供了类似的错误。那么在IDE中编辑groovy脚本时有没有办法使用Grape下载sources / javadoc？

Answer 1

您链接的文档还提到了使用classifier属性的可能性，这似乎更有效（Grape确实会抓住相应的jar）：

@Grab(group='org.apache.commons', module='commons-lang3', version='3.4', classifier='sources')

但是，它看起来像Grape support in Idea is incomplete。为了让Idea使用抓取的包，您需要将光标放在@Grab注释上，按alt-enter并手动获取工件。然后，您可以从projet结构的设置将它们复制到模块库中。这似乎对我有用，虽然我也觉得它无视使用Grape的全部意义......
