java.lang.ExceptionInInitializerError groovy编译器加载错误

Question

当我执行 JUnit 测试用例时，出现以下错误。我正在使用 Grails 域测试用例的 Expectations 插件。

BuildConfig.groovy 文件代码：

plugins {
   compile ":domain-expectations:0.6.1"
}

我收到的错误：

这意味着类路径上有 2 个版本的 Groovy：2.3.10 和 2.3.7。一个可能是 Grails 带来的，另一个是插件带来的，这意味着它们不兼容。您应该尝试将 Groovy 从插件依赖项中排除。
