Question

We are getting error: Code coverage error:

[jacoco:coverage] Enhancing java with coverage
     [java] Error: Could not find or load main class **\*.class
     [java] Java Result: 1
[jacoco:coverage] Enhancing junit with coverage
    [junit] Test **/*Test FAILED

我们正在使用jacoco代理进行代码覆盖率报告并使用ant它显示构建成功但jacoco.exec仅为1 kb并且编译时出错也就是为什么我们在build.xml中注释掉了我们也超过了错误。

我的build.xml看起来像：

<?xml version="1.0" encoding="UTF-8"?>

Answer 1

<java classname="xxx">部分告诉JaCoCo实际运行您的应用程序。因此，需要成为具有main方法的类：不只是**/*.class。它不会接受那里的通配符。

有关示例，请参阅http://www.eclemma.org/jacoco/trunk/doc/ant.html。
