詹金斯jacoco插件空报告

Question

我有一个项目,我使用Jacoco来计算代码覆盖率.我在这里使用maven配置:

http://www.petrikainulainen.net/programming/maven/creating-code-coverage-reports-for-unit-and-integration-tests-with-the-jacoco-maven-plugin/

使用Jenkins,我运行"mvn clean install test".它在/ target/site/jacoco-ut /文件夹中生成报告.如果我打开index.html文件,我会看到:

但是当我在jenkins工作中打开JaCoCo Coverage报告时,我看到了:

它说每个测试覆盖0%的代码.我不明白为什么我在html报告中没有相同的结果.

而我的jenkins配置:

我的错误是什么？

Answer 1

我发现詹金斯问题与我的问题类似：

https://issues.jenkins-ci.org/browse/JENKINS-28652

该错误是由jacoco版本引起的。0.7.5.201505241946版本有bug。我切换到版本 0.7.4.201502262128，现在它可以工作了。
