通過 maven 把項目打成 jar

         <build>
                <finalName>test</finalName>
        
                <plugins>
                    <plugin>
                        <groupId>org.apache.maven.plugins</groupId>
                        <artifactId>maven-compiler-plugin</artifactId>
                        <version>3.6.0</version>
                        <configuration>
                            <source>1.8</source>
                            <target>1.8</target>
                            <encoding>UTF-8</encoding>
                        </configuration>
                    </plugin>
        
        
                    <plugin>
                        <groupId>org.apache.maven.plugins</groupId>
                        <artifactId>maven-jar-plugin</artifactId>
                        <version>2.4</version>
                        <configuration>
                            <archive>
                                <manifest>
                                    <mainClass>io.Test</mainClass>
                                </manifest>
                            </archive>
                        </configuration>
                    </plugin>
                </plugins>
         </build>

啟動腳本

java -Xmx4000m -Xms4000m -Xmn1024m -XX:MetaspaceSize=128M -XX:+HeapDumpOnOutOfMemoryError -XX:+PrintGCDateStamps -XX:HeapDumpPath=/Users/Downloads/ -verbose:gc -XX:+PrintHeapAtGC -XX:+PrintGCDetails -XX:+PrintGCCause -Xloggc:/Users/Downloads/gc_app.log -jar $BASE/test.jar

不能把JVM的參數(shù) 放在 -jar 后面，原因如下圖所示
