Maven使用cobertura-maven-plugin单元测试--测试覆盖率（加减乘除的测试）

Maven使用cobertura-maven-plugin单元测试–测试覆盖率（加减乘除的测试）

遇到的问题：
Failed to execute goal org.codehaus.mojo:cobertura-maven-plugin:2.5.1:instrument (default) on project MavenTest: Execution default of goal org.codehaus.mojo:cobertura-maven-plugin:2.5.1:instrument failed: A required class was missing while executing org.c

解决办法：删maven仓库重新下载那些东西。cmd下搞

1.开始：
使用cobertura-maven-plugin
主要命令 test、cobertura:cobertura
