spring_boot打jar包及打包错误的解决方法

问题产生及解决

        对于刚接手spring_boot的人,可能会感觉到很茫然无措,看到书上写的spring_boot是直接打包成jar包,使用java -jar *运行。然而却不知道该怎么打包。而创建spring_boot以后在pom文件中会安装spring_boot打包插件,此时我们会看到如下几个选项:

  • pom文件内容如下:

  • 在idea的右侧我们会看如下选项

如果此时我们直接点击repackage,则打包时会出现如下错误:

[ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:1.4.3.RELEASE:repackage (default-cli) on project springboot_1: Execution default-cli of goal org.springframework.boot:spring-boot-maven-plugin:1.4.3.RELEASE:repackage failed: Source must refer to an existing file -> [Help 1]
[ERROR]
[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.
[ERROR] Re-run Maven using the -X switch to enable full debug logging.
[ERROR]
[ERROR] For more information about the errors and possible solutions, please read the following articles:
[ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/PluginExecutionException

Process finished with exit code 1

正确的打包方法是:

直接使用maven的package命令,即可完成打包,若有新的内容添加,可以使用spring-boot-maven-plugin的repackage命令.详细步骤如下图:
