maven-shade-plugin
maven 工程超级打包,包括工程依赖及对依赖包的重命名。
如下:打包并配置MainClass
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>1.4</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
<configuration>
<filters>
<filter>
<artifact>*:*</artifact>
<excludes>
<exclude>META-INF/config.temp</exclude>
</excludes>
</filter>
</filters>
<transformers>
<transformer

Maven Scope
Dependency Scope
在POM 4中,<dependency>中还引入了<scope>,它主要管理依赖的部署。目前<scope>可以使用5个值:
* compile,缺省值,适用于所有阶段,会随着项目一起发布。
* provided,类似compile,期望JDK、容器或使用者会提供这个依赖。如servlet.jar。
* runtime,只在运行时使用,如JDBC驱动,适用运行和测试阶段。
* test,只在测试时使用,用于编译和运行测试代码。不会随项目发布。
* system,类似provided,需要显式提供包含依赖的jar,Maven不会在Repository中查找它。
依赖范围控制哪些依赖在哪些classpath 中可用,哪些依赖包含在一个应用中。让我们详细看一下每一种范围:
compile (编译范围)
compile是默认的范围;如果没有提供一个范围,那该依赖的范围就是编译范围。编译范围依赖在所有的classpath 中可用,同时它们也会被打包。
provided (已提供范围)
provided 依赖只有在当JDK 或者一个容器已提供该依赖之后才使用。例如, 如果你开发了一个web 应用,你可能在编译 classpath 中需要可用的Servlet API 来编译一个servlet,但是你不会想要在打包好的WAR 中包含这个Servlet API;这个Servlet API JAR 由你的应用服务器或者servlet 容器提供。已提供范围的依赖在编译classpath (不是运行时)可用。它们不是传递性的,也不会被打包。
runtime (运行时范围)
runtime 依赖在运行和测试系统的时候需要,但在编译的时候不需要。比如,你可能在编译的时候只需要JDBC API JAR,而只有在运行的时候才需要JDBC
驱动实现。
test (测试范围)
test范围依赖 在一般的编译和运行时都不需要,它们只有在测试编译和测试运行阶段可用。
system (系统范围)
