springboot项目打包并部署到Tomcat上及报错处理

一、打包springboot项目

双击clean再双击package

报错：Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.13.0:compile (default-compile) on project springboot_vue: The plugin org.apache.maven.plugins:maven-compiler-plugin:3.13.0 requires Maven version 3.6.3 -> [Help 1]

方法1：查看file->setting，Build,Executive,Deployment中的Build Tools下的Maven下的Importing 、Runner、Complier -> Java Compiler有关Java版本是否不为空或者正确

方法2：查看file->projectStructure，Project、Modules、SDKs是否为空或正确

以上两个方法没有解决我的问题

我的解决方法：重新装一遍Maven version 3.6.3，因为我的Maven版本之前是3.6.1(这个方法成功打包)

setting中重新配置Maven

二、部署到Tomcat

将jar包复制到tomcat安装目录下的webapps文件夹下面

在当前目录有点打开cmd

输入命令：java -jar xxxxx.jar

如果在启动时报错：

xxxxx.jar中没有主清单属性

pom.xml文件中加上：

     <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

启动失败：14404，端口占用

可能是你的tomcat服务器开着（startup.bat），需要关掉
