问题发现

最近使用maven分析jar包的时候遇到了一个很搞的问题。我在terminal中输入指令mvn dependency:analyze，出现如下报错

分析问题发现是 zip file（就是jar包） 打开错误。但maven没告诉我到底是哪个jar包出问题了，只告诉我是dianming-common模块依赖的jar包出问题了，我想查看更详细的信息，于是添加了如下参数

mvn dependency:analyze -e -X重新运行。

好消息，maven输出了更多的信息，坏消息，maven还是没告诉我到底是哪个zip file炸了

全部的报错信息

我很想吐槽，你倒是把错误的zip file告诉我老铁，告诉我错误模块我排查个der。
我查遍了网上资料都找不到解决方案，于是只能去debug maven的源码。具体的debugger方式学习了这个大佬的文章。如何debug(调试) maven 插件？ - 知乎 (zhihu.com)

tip: 这个大佬的文章的某些地方不适用于我所遇到的问题，因此下文所写与大佬文章有较大不同

调试Maven

1. 查看maven版本

cmd中输入mvn -version即可查看版本（我配置了环境变量。如果没有配置，就去下载maven的目录下查看），我的是maven 3.5.4。源码版本需要下载3.5.4

2. 下载对应版本的maven源码

apache/maven: Apache Maven core (github.com)

这是maven的GitHub官方连接，点击tag，下载对应版本的代码

3. 打开maven源码，配置启动选项

用idea打开下载的源码，配置启动选项，具体如下：

• 点击Edit Configurations
• 点击➕
• 选择Remote
• 配置Host为localhost【根据自己需求调整】
• 配置Port为8000【一般都是8000，后文会说明】

这样就算配置完maven源码的启动参数，接下来我们需要到自己的项目中，开启maven的debug模式即可。

启动maven debug模式

启动maven的debug模式很简单，将平时的mvn指令改为mvnDebug即可。现在回到我们自己的项目，在终端处输入如下指令mvnDebug dependency:analyze -e -X，此时maven开启debug模式，监听8000端口

tip: 需要注意，8000和Maven源码项目配置的port一致。

进入maven 源码，打断点调试

tip: 具体的调试方式需要具体问题具体分析，我遇到的问题代码时ZipFile的225行（由之前maven输入的错误信息中得到的），我能找到距离该处最近的代码是DefaultBuildPluginManager的137行，因此我是按照下述操作debug

进入maven源码项目，在DefaultBuildPluginManager的137行处打下断点，进行调试。

我自己的项目需要在此处打断点运行18次，然后再报错代码处：ZipFile的224行，打下断点。放行断点后代码中止到224行。当继续往下运行时发现代码抛出异常，因此定位到问题jar包：D:\repository\org\aspectj\aspectjweaver\1.9.6\aspectjweaver-1.9.6.jar

找jar包算账

定位到问题jar包后，我们在文件管理器中搜索D:\repository\org\aspectj\aspectjweaver\1.9.6\aspectjweaver-1.9.6.jar。发现确实无法打开，至此问题jar包定位成功！
