maven-compiler-plugin
这个插件是用来编译源代码的
例如报错static import declarations are not supported in -source 1.3 ,这是因为编译的时候默认是1.3版本.可以设定编译器的版本为1.6
target版本一定大于等于source版本

maven-dependency-plugin
我们在IDE的环境里编译和执行代码的时候，那是直接引用一些类库。但是在我们实际部署的环境里，那边很可能就一个java执行环境，不可能有源代码和IDE。这个时候，我们需要将源代码编译打包。这个时候的一个问题就是如果我们引用的库很多的话，我们希望能够把他们统一打包到一个目录下，比如lib文件夹。这样部署执行的时候只需要将编译生成的程序jar包和依赖包文件夹拷到特定目录去执行

maven-shade-plugin
一些非springboot项目打成可执行的jar包，主要打发布包使用，通过一个xml文件定义更多自定义打包项
assembly与shade的区别
对xsd文件的处理方式不同，assembly是找到一个放入最终打出的jar包里，但是这样有个问题是当工程依赖到不同版本的依赖包时只能将某一个版本的xsd配置文件放入最终打出的jar包里，这就有可能遗漏了一些版本的xsd的本地映射，会报错；shade插件打包时在对spring.schemas文件处理上，它能够将所有jar里的spring.schemas文件进行合并，在最终生成的单一jar包里，spring.schemas包含了所有出现过的版本的集合
maven-surefire-plugin
Maven通过Maven Surefire Plugin插件执行单元测试。（通过Maven Failsafe Plugin插件执行集成测试），也可用于打包时跳过测试
