安装mvnw
mvn -N io.takari:maven:wrapper

#mvn wrapper:wrapper
#mvn wrapper:wrapper -Dmaven=3.9.8
mvn clean install
./mvnw clean install

运行spring-boot程序
./mvnw sprint-boot:run
java -jar ./target/jarfile.jar com.mars.demo.Application

打包配置

方法一：使用maven-jar-plugin和maven-dependency-plugin 
方法二：使用maven-assembly-plugin (推荐) 
方法三：使用maven-shade-plugin 
方法四：使用onejar-maven-plugin 
方法五：使用spring-boot-maven-plugin 
方法六：使用tomcat7-maven-plugin

使用maven-assembly-plugin 
maven-assembly-plugin可以将所有的东西都打包到一个jar包中
<plugin>
    <groupId>org.apache.maven.plugins</groupId><artifactId>maven-assembly-plugin</artifactId>
    <executions>
    <execution>
        <phase>package</phase>
        <goals>
            <goal>single</goal>
        </goals>
        <configuration>
            <archive>
                <manifest>
                <mainClass>
                    com.michealyang.jetty.embeded.EmbeddedJettyServer</mainClass>
                </manifest>
            </archive>
            <descriptorRefs>
                <descriptorRef>jar-with-dependencies</descriptorRef>
            </descriptorRefs>
        </configuration>
        </execution>
    </executions>
</plugin>

使用onejar-maven-plugin 
This provides custom classloader that knows how to load classes and resources from jars inside an archive, instead of from jars in the filesystem.
<plugin>
    <groupId>com.jolira</groupId><artifactId>onejar-maven-plugin</artifactId>
    <executions>
        <execution>
            <configuration>
                <mainClass>org.baeldung.executable.
                    ExecutableMavenJar
                </mainClass>
                <attachToBuild>true</attachToBuild>
                <filename>
                    ${project.build.finalName}.${project.packaging}
                </filename>
            </configuration>
            <goals>
                <goal>one-jar</goal>
            </goals>
        </execution>
    </executions>
</plugin>

使用spring-boot-maven-plugin 
能同时打可执行jar包和war包 This allows to package executable jar or war archives and run an application “in-place”.
<plugin>
    <groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId>
    <executions>
        <execution>
        <goals>
            <goal>repackage</goal>
        </goals>
        <configuration>
            <classifier>spring-boot</classifier>
            <mainClass>
                org.baeldung.executable.ExecutableMavenJar
            </mainClass>
        </configuration>
        </execution>
    </executions>
</plugin>

使用tomcat7-maven-plugin 
可打包成一个web工程类型的jar包。其实是内嵌了一个tomcat在里面。
<plugin>
    <groupId>org.apache.tomcat.maven</groupId>
    <artifactId>tomcat7-maven-plugin</artifactId>
    <version>2.0</version>
    <executions>
        <execution><id>tomcat-run</id>
        <goals>
            <goal>exec-war-only</goal>
        </goals>
        <phase>package</phase>
        <configuration>
            <path>/</path>
            <enableNaming>false</enableNaming)
            <finalName>webapp.jar</finalName)
            <charset>utf-8</charset>
        </configuration>
        </execution>
    </executions>
</plugin>

更改当前环境
update-alternatives --config java
update-alternatives --config javac
