問題產生及解決

對于剛接手spring_boot的人，可能會感覺到很茫然無措，看到書上寫的spring_boot是直接打包成jar包，使用java -jar *運行。然而卻不知道該怎么打包。而創建spring_boot以后在pom文件中會安裝spring_boot打包插件，此時我們會看到如下幾個選項：

pom文件內容如下：

在idea的右側我們會看如下選項

如果此時我們直接點擊repackage,則打包時會出現如下錯誤：

[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

正確的打包方法是：

直接使用maven的package命令，即可完成打包，若有新的內容添加，可以使用spring-boot-maven-plugin的repackage命令.詳細步驟如下圖：
