maven 的几个重要的配置文件：super pom & 生命周期默认绑定的配置文件
这几个配置文件都在 maven 的 安装 目录的 lib 目录中
1. super pom.
在 maven-model-builder-{version}.jar 包的
org/apache/maven/model 中的 pom-4.0.0.xml 这个文件
所有的pom 文件都继承该 pom 文件。摘抄如下：

2. 生命周期绑定文件
在 maven-core-{version}.jar 包中
META-INF/plexus/components.xml 中。重要的几个绑定：
2.1 packing 类型 为 war 时的默认绑定
1 2 <component> 3 <role>org.apache.maven.lifecycle.mapping.LifecycleMapping</role> 4 <role-hint>war</role-hint> 5 <implementation>org.apache.maven.lifecycle.mapping.DefaultLifecycleMapping</implementation> 6 <configuration> 7 <lifecycles> 8 <lifecycle> 9 <id>default</id> 10 11 <phases> 12 <process-resources> 13 org.apache.maven.plugins:maven-resources-plugin:2.6:resources 14 </process-resources> 15 <compile> 16 org.apache.maven.plugins:maven-compiler-plugin:3.1:compile 17 </compile> 18 <process-test-resources> 19 org.apache.maven.plugins:maven-resources-plugin:2.6:testResources 20 </process-test-resources> 21 <test-compile> 22 org.apache.maven.plugins:maven-compiler-plugin:3.1:testCompile 23 </test-compile> 24 <test> 25 org.apache.maven.plugins:maven-surefire-plugin:2.12.4:test 26 </test> 27 <package> 28 org.apache.maven.plugins:maven-war-plugin:2.2:war 29 </package> 30 <install> 31 org.apache.maven.plugins:maven-install-plugin:2.4:install 32 </install> 33 <deploy> 34 org.apache.maven.plugins:maven-deploy-plugin:2.7:deploy 35 </deploy> 36 </phases> 37 38 </lifecycle> 39 </lifecycles> 40 </configuration> 41 </component>
2.2 packing 类型 为 jar 时的默认绑定
