unit-testing - java.lang.ExceptionInInitializerError groovy编译加载错误

Question

我在执行 JUnit 测试用例时出现以下错误。我正在为 Grails 域测试用例使用 Expectations 插件。

BuildConfig.groovy 文件代码:

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

我遇到的错误:

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自带的，一个是插件自带的，就是不兼容。您应该尝试从插件依赖项中排除 Groovy。
