Grails coverage插件提供格式错误的类名错误

Question

几周后，我们的Jenkins CI服务器出现了一个我无法解决的错误。我尝试了http://grails.1312388.n4.nabble.com/code-coverage-plugin-running-unit-and-integration-tests-separately-td4632709.html的解决方案但是没有用。我也尝试禁用分叉模式进行测试，但这会产生同样的错误。所有测试都通过，但coverage插件会出错。

我执行的命令是grails test-app unit: --plain-output --stacktrace --non-interactive --verbose -coverage -xml。当我只运行集成测试（grails test-app integration: --plain-output --stacktrace --non-interactive --verbose -coverage -xml）时，coverage插件工作正常。 我使用的是Java版本1.7.0_80和Grails 2.4.2。

这是堆栈跟踪：
