Java Maven项目打jar包方法

Posted 2022-09-23 一休Q_Q

使用assembly的方式

1. 配置assemby文件，定义不打进去的相关包，依赖的包会压缩成一个大的jar包

..\\..\\..\\src\\main\\resources\\3rd-jar-zztjapp.xml

2.在pom文件添加文件配置

<plugin>

              <artifactId>maven-assembly-plugin</artifactId>           

              <configuration>

                  <!--3rd-jar-agent thirdparty -->

                  <!--KMinerClass-agent agent -->

                  <descriptors>

                     <descriptor>src/main/resources/3rd-jar-zztjapp.xml</descriptor>

                  </descriptors>

                  <appendAssemblyId>false</appendAssemblyId>

                  <finalName>zztjapp</finalName>

              </configuration>

              <!-- 以下这段表明 maven-assembly-plugin的single goal被绑定在package phase上了，注释掉避免每次package时自动生成第三方jar包 -->

              <!-- <executions> <execution> <id>make-assembly</id> <phase>package</phase>

                  <goals> <goal>single</goal> </goals> </execution> </executions> -->

           </plugin>

1. 执行打包代码

mvn clean install -DskipTests

mvn assembly:assembly

使用package方式

将下面代码拷贝到pom文件中，产出的依赖包会放入lib文件夹下

<build>

<plugins>

<plugin>

<groupId>org.apache.maven.plugins</groupId>

<artifactId>maven-jar-plugin</artifactId>

<configuration>

<!-- 包含文件配置，现在只打包 com 文件夹 -->

<includes>

<include>

**/com/**

</include>

</includes>



<archive>

<manifest>

<!-- 配置加入依赖包 -->

<addClasspath>true</addClasspath>

<classpathPrefix>lib/</classpathPrefix>

<useUniqueVersions>false</useUniqueVersions>

<!-- Spring Boot 启动类(自行修改) -->

<mainClass>com.server.EnterpriseApp</mainClass>

</manifest>

<manifestEntries>

<!-- 外部资源路径加入 manifest.mf 的 Class-Path -->

<Class-Path>resources/</Class-Path>

</manifestEntries>

</archive>

<!-- jar 输出目录 -->

<outputDirectory>$project.build.directory/</outputDirectory>

</configuration>

</plugin>

<plugin>

<groupId>org.apache.maven.plugins</groupId>

<artifactId>maven-dependency-plugin</artifactId>

<!-- 复制依赖 -->

<executions>

<execution>

<id>copy-dependencies</id>

<phase>package</phase>

<goals>

<goal>copy-dependencies</goal>

</goals>

<configuration>

<!-- 依赖包 输出目录 -->

<outputDirectory>$project.build.directory/lib</outputDirectory>

</configuration>

</execution>

</executions>

</plugin>

<plugin>

<artifactId>maven-resources-plugin</artifactId>

<!-- 复制资源 -->

<executions>

<execution>

<id>copy-resources</id>

<phase>package</phase>

<goals>

<goal>copy-resources</goal>

</goals>

<configuration>

<resources>

<resource>

<directory>src/main/resources</directory>

</resource>

</resources>

<!-- 资源文件 输出目录 -->

<outputDirectory>$project.build.directory/resources</outputDirectory>

</configuration>

</execution>

</executions>

</plugin>

<plugin>

<groupId>org.apache.maven.plugins</groupId>

<artifactId>maven-compiler-plugin</artifactId>

<configuration>

<source>8</source>

<target>8</target>

</configuration>

</plugin>

</plugins>

</build>

执行打包脚本

mvn clean package -Dmaven.test.skip=true

调用接口执行

java -cp "ts-test_lib/*" com.cws.test.KMAnaTest "./dic" "./性能测试" "NoProcess" "1"

注意：某些时候，由于eclipse等工具配置问题，会报

将编码加入pom的<properties>中。

<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
