引起:java.lang.ClassNotFoundException:net.sourceforge.cobertura.coveragedata.HasBeenInstrumented

Question

我们已经安装了我们的应用程序版本(在生成应用程序包之前没有包含任何工具或cobertura jar).

安装完成后,我们使用cobertura对所有jar进行了检测,并在java classpath中包含了cobertura jar文件.但在启动应用程序时它会给出以下错误.

任何输入都会有所帮助,谢谢.

Java版"1.7.0_25"
cobertura ver 1.9.4.1

您应该使用 -Xbootclasspath 将 cobetura.jar 添加到引导类。更多信息：https://docs.oracle.com/javase/8/docs/technotes/tools/findingclasses.html 需要执行此操作才能加载 cobetura 类，这是加载应用程序类所必需的。
