IDEA java 编译和打包成jar包

第一次用IDEA 也是第一次打包成jar包.
按照网上的教程进行打包发现.怎么都不行,
BUILD FAILURE
报错信息里面也是一堆无用的信息.
信息如下.

研究了1个小时,
最后总结一下,
在命令行里面直接执行 mvn install 所报的错误是没啥意义的.即便是加了-X 参数也没啥用.
要在IDEA里面用鼠标执行的时候报错内容才有价值.

第一步要看看编译是否成功.
在这里插入图片描述
第二步:确认无问题.

第三步:检查maven, 目录下D:\apache-maven-3.6.3\conf\settings.xml 中的文件配置.要加上国内的阿里云会有效提高下载jar包的速度. 我的配置如下 ,加了. 阿里云的镜像源

<mirrors> 
       <mirror>
            <id>alimaven</id>
            <mirrorOf>central</mirrorOf>
            <name>aliyun maven</name>
            <url>http://maven.aliyun.com/nexus/content/repositories/central/</url>
        </mirror>
        <mirror>
            <id>nexus-aliyun</id>
            <mirrorOf>*</mirrorOf>
            <name>Nexus aliyun</name>
            <url>http://maven.aliyun.com/nexus/content/groups/public</url>
        </mirror>
        <!-- 中央仓库1 -->
        <mirror>
            <id>repo1</id>
            <mirrorOf>central</mirrorOf>
            <name>Human Readable Name for this Mirror.</name>
            <url>http://repo1.maven.org/maven2/</url>
        </mirror>
    
        <!-- 中央仓库2 -->
        <mirror>
            <id>repo2</id>
            <mirrorOf>central</mirrorOf>
            <name>Human Readable Name for this Mirror.</name>
            <url>http://repo2.maven.org/maven2/</url>
        </mirror>
  </mirrors>

第四步: 先清理一下,
在这里插入图片描述
第五步:检查生成的目标是jar包还是war包.

第六步: 执行maven install
在这里插入图片描述
到这一步已经打包成功了.

第七步: 在命令行中执行java命令. java -r bsn-java.jar 即可启动网站.

如果出现一些打不了包的情况. 或者版本不对的情况. 请到
https://mvnrepository.com/
查询包的对应版本.
