Maven 打 Jar 包體積縮小

1依賴拆配置設定置

隻需要在項目pom.xml檔案中添加下面的配置：

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
            </configuration>
        </plugin>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <fork>true</fork>
                <finalName>${project.build.finalName}</finalName>
                <!--解決windows指令行視窗中文亂碼-->
                <jvmArguments>-Dfile.encoding=UTF-8</jvmArguments>
                <layout>ZIP</layout>
                <includes>
                    <!--這裡是填寫需要包含進去的jar，
                        必須項目中的某些子產品，會經常變動，那麼就應該将其坐标寫進來
                        如果沒有則non-exists ，表示不打包依賴
                    -->
                    <include>
                        <groupId>non-exists</groupId>
                        <artifactId>non-exists</artifactId>
                    </include>
                </includes>
            </configuration>
            <executions>
                <execution>
                    <goals>
                        <goal>repackage</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
        <!--此插件用于将依賴包抽出-->
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-dependency-plugin</artifactId>
            <executions>
                <execution>
                    <id>copy-dependencies</id>
                    <phase>package</phase>
                    <goals>
                        <goal>copy-dependencies</goal>
                    </goals>
                    <configuration>
                        <outputDirectory>${project.build.directory}/lib</outputDirectory>
                        <excludeTransitive>false</excludeTransitive>
                        <stripVersion>false</stripVersion>
                        <includeScope>runtime</includeScope>
                    </configuration>
                </execution>
            </executions>
        </plugin>
        <plugin>
            <artifactId>maven-surefire-plugin</artifactId>
            <configuration>
                <skip>true</skip>
            </configuration>
        </plugin>
    </plugins>
</build>      

2 再次建構

mvn clean package -DskipTests=true

mvn clean kotlin:compile package -Dmaven.test.skip=true -f pom.xml      

發現​

​target​

​​目錄中多了個​

​lib​

​​檔案夾，裡面儲存了所有的​

​依賴jar​

​

nohup java -jar -Dloader.path=./lib ccue-server.jar --spring.profiles.active=dev &
