相关疑难解决方法(0)

根据前两个答案:maven dependencies groovy.我正在尝试使用来自org.codehaus.gmaven的GMaven-plugin,使用Maven编译混合Java 6 + Groovy项目.直到昨天我们使用的是旧1.6.0版本的Groovy(在我们最终完成它之后从未改变它),但由于1.7.0现在稳定,我认为我们会改用它.

如果只是那么简单......我现在遇到的问题似乎有两个方面:

• Groovy 1.6以某种方式仍然被选为默认值.(如下面的stacktrace中所示)
• groovy:generateStubs因构建错误而停止:意外节点:节点[7:1,64,注释]

有谁知道如何解决上述两个问题,或者可以提供一个工作pom来编译与Maven Java 6代码混合的Groovy 1.7代码？

使用gmaven/groovy.maven/groovy.maven.gmaven编译旧版本的Groovy时,有很多令人困惑/矛盾/过时的文档,现在真的没有帮助.

作为参考,这是我的pom.xml和Maven -e输出的一部分:

我在课程开头有这个:

@Grab(group = 'org.ccil.cowan.tagsoup', module = 'tagsoup', version = '1.2')
class MyClass{...

我正在尝试对这个类进行单元测试,但每当我尝试运行JUnit 4测试时,我都会收到此错误:
