如何调试Maven软件的源代码

和调试maven插件方法一样

1. 修改maven源代码

2. 打包模块apache-maven，生成apache-maven-x.x.x-bin.tar.gz

3. 解压上面的压缩包，生成目录apache-maven-x.x.x，在某个maven项目下执行/根路径/apache-maven-x.x.x/bin/mvnDebug clean install -DskipTests

4. 在maven源码项目里设置远程调试，如下图，选择相应的模块，进行调试

5. 当执行的Java虚拟机jvm里的相应字节码时，就会在相应的源码断点里停止

   

6. 断点设置

   

m2.conf

mac下的路径/usr/local/Cellar/maven/3.6.0/libexec/bin/m2.conf，根据第一行代码，找到上面的断点位置

main is org.apache.maven.cli.MavenCli from plexus.core

set maven.conf default ${maven.home}/conf

[plexus.core]
load       ${maven.conf}/logging
optionally ${maven.home}/lib/ext/*.jar
load       ${maven.home}/lib/*.jar
