由于缺少库而导致构建失败 [英] Build failure due to missing libraries

问题描述

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile (default-compile) on project spring-intergation: Compilation failure: Compilation failure:
[ERROR] \spring-intergation\src\main\java\uk\co\dd\spring\domain\User.java:[3,24] package javax.persistence does not exist
[ERROR] \spring-intergation\src\main\java\uk\co\dd\spring\domain\User.java:[4,24] package javax.persistence does not exist

[ERROR] \spring-intergation\src\main\java\uk\co\dd\spring\domain\User.java:[9,1] cannot find symbol

但是我通过右键单击项目并添加外部jar，在eclipse中添加了所有库.

But i have added all the libraries in my eclipse by right clicking the project and adding the external jars.

当我尝试运行mvn编译时，我得到了这些错误，同时也丢失了许多其他jar.

When i try to run mvn compile i get these errors with a lot of other jars also missing.

我应该对POM.xml做任何事情

Should i do anything with POM.xml

推荐答案

将此添加到您的依赖项

<dependency>
  <groupId>javax.persistence</groupId>
  <artifactId>persistence-api</artifactId>  
  <version>1.0</version>
</dependency>
