Maven “三叶草”失败；未找到Clover数据库，正在跳过报告生成“；

我正试图将Clover添加到我的maven（groovy）项目中，以获得一些代码覆盖率结果。但是，它无法生成代码覆盖率报告。 报告是空的

我的src文件位于src/main/groovy中，我的测试位于src/test/groovy中

当我跑步时：

mvn清洁三叶草：设置测试三叶草：仪器三叶草：聚合三叶草：三叶草

生成日志：

[INFO] No Clover instrumentation done on source files in: [/home/xxx/workspace/yyy/src/main/java, /home/xxx/workspace/yyy/target/generated-sources/groovy-stubs/main] as no matching sources files found (JAVA_LANGUAGE)
[INFO] No Clover instrumentation done on source files in: [/home/xxx/workspace/yyy/src/test/java, /home/xxx/workspace/yyy/src/test/groovy] as no matching sources files found (JAVA_LANGUAGE)

事实上，如果我在树中查找任何数据库文件
