本文主要总结最近一段时间使用maven时,遇到需要maven plugins的一些简单总结。
1)在Build下重新指定最终打包报名
<build> <!--最终打包的包名,如果这里不指定,则默认包名为:artifactId-version.jar(com-test-project-1.0-SNAPSHOT.jar)--> <finalName>The-Test-Pro</finalName> ... </build>
2)Maven Repository上以外的自定义包引入,以及如何设置才能被打包进来
a)在dependencies下引入lib下的jar
<dependency> <groupId>org.apache.spark</groupId> <artifactId>spark-core_2.11-1.5.2.logging</artifactId> <version>2.11</version> <scope>system</scope> <systemPath>${project.basedir}/lib/spark-core_2.11-1.5.2.logging-2.11.jar</systemPath> </dependency>
b)在maven-compiler-plugin配置包时将/lib下的包打包进来
<!--代码编译,指定扩展包在lib下,且打包时将/lib下的包打包进来--> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>2.3.2</version> <configuration> <encoding>UTF-8</encoding> <source>1.8</source> <target>1.8</target> <showWarnings>true</showWarnings> <compilerArguments> <extdirs>${project.basedir}/lib</extdirs> </compilerArguments> </configuration> </plugin>
3)通过maven-assembly-plugin设置编译fat包
<!-- 在pom中配置了若干依赖,需要将pom中所有的依赖全部打包进一个jar包中,可以选择的方案有maven-assembly-plugin 此时,在Target下会打包一个finalName-jar-with-dependencies.jar,(不指定finalName时:artifactId-version-with-dependencies.jar) --> <plugin> <artifactId>maven-assembly-plugin</artifactId> <configuration> <descriptorRefs> <descriptorRef>jar-with-dependencies</descriptorRef> </descriptorRefs> <archive> <manifest> <mainClass>com.main.Invoker</mainClass> </manifest> </archive> </configuration> <executions> <execution> <id>make-assembly</id> <phase>package</phase> <goals> <goal>single</goal> </goals> </execution> </executions> </plugin>
4)使用maven-dependency-plugin拷贝依赖的jar包到/target/lib目录
<!-- 拷贝依赖的jar包到/target/lib目录 --> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-dependency-plugin</artifactId> <executions> <execution> <id>copy</id> <phase>package</phase> <goals> <goal>copy-dependencies</goal> </goals> <configuration> <outputDirectory> ${project.build.directory}/lib </outputDirectory> </configuration> </execution> </executions> </plugin>
