使用maven-compiler-plugin以及maven-shade-plugin完成maven项目打包

最近负责一个纯maven项目(项目需求尽量轻量化)，需要自己完成打包工作.

因此，基于maven-compiler-plugin以及maven-shade-plugin完成项目的打包工作.

其中:

• maven-compiler-plugin负责项目编译；
• maven-shade-plugin负责最终的打包操作.

以下所示操作，均在pom.xml文件中进行.

项目基本属性

<groupId>com.test</groupId>
<artifactId>app</artifactId> //
<version>0.1.0</version>
<packaging>jar</packaging> <properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
<java.version>1.8</java.version>
</properties>


添加插件

<build>
<plugins> <!-- 编译java项目-->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<source>${java.version}</source>
<target>${java.version}</target>
</configuration>
</plugin> <!-- 创建一个fat jar,包含所有必须的依赖 -->
<!-- 根据自己的main函数替换<mainClass>...</mainClass>中的配置 -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>3.0.0</version>
<executions>
<!-- Run shade goal on package phase -->
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
<configuration>
<artifactSet>
<!-- 指定不需要打包的文件(可以使用通配符) -->
<excludes>
<exclude>org.apache.flink:force-shading</exclude>
<exclude>com.google.code.findbugs:jsr305</exclude>
<exclude>org.slf4j:*</exclude>
<exclude>log4j:*</exclude>
</excludes>
</artifactSet>
<filters>
<filter>
<!-- Do not copy the signatures in the META-INF folder.
Otherwise, this might cause SecurityExceptions when using the JAR. -->
<artifact>*:*</artifact>
<excludes>
<exclude>META-INF/*.SF</exclude>
<exclude>META-INF/*.DSA</exclude>
<exclude>META-INF/*.RSA</exclude>
</excludes>
</filter>
</filters>
<transformers>
<transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
<mainClass>com.test.app.Application</mainClass>
</transformer>
</transformers>
</configuration>
</execution>
</executions>
</plugin>
</plugins>


Tips:

maven-shade-plugin比较强大，还可以解决打包文件中的依赖冲突,读者可以自行寻找相关文章.
