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build.xml代理进行代码覆盖率报告，并使用ant，它显示构建是成功的，但jacoco.exec只有1kb大小，在编译时得到错误，这就是为什么我们在build.xml中注释掉了它，我们也得到了上面的错误。

我的build.xml看起来像这样：

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

<java classname="xxx">部分告诉JaCoCo实际运行您的应用程序。所以需要是包含main方法的类:而不仅仅是**/*.class。它不接受那里的通配符。

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