Question

我已经阅读了大部分类似问题的答案，但没有一个能够回答我的问题。

我在pom文件中的个人资料如下所示：

当我使用maven目标clean install -P test-coverage

运行我的jenkins工作时

我在Jenkins日志中看到了这个：

这就是我对Jacoco的Jenkins配置的看法：

Answer 1

在我的情况下，我使用的是jacocoant 0.6，jenkins的jaCoCo插件是2.2.0。来自jaCoCo插件github页面：

2.0.0及更高版本要求使用JaCoCo 0.7.5或更高版本，如果您的项目仍使用JaCoCo 0.7.4，该插件将不再显示任何代码覆盖率数字！在这种情况下，请使用版本1.0.19，直到您可以更新代码库中的jacoco。 https://github.com/jenkinsci/jacoco-plugin

Answer 2

在我的情况下，它无法获取exec文件。

这是因为我的构建目录与Jenkins作业的WORKSPACE不同。当我将构建目录更改为WORKSPACE时，魔术就发生了。

Answer 3

在我的情况下，Jacoco插件是1.0.19，但我使用的是Jacoco-maven-plugin 0.7.9，它不兼容。

所以，将Jacoco-maven-plugin改为0.7.4.x后。我对詹金斯有正确的报道

Jacoco代码覆盖率显示Jenkins的覆盖率为0％
