java - 当我在我的项目库中包含 EclipseLink-ModelGen(JPA 2.1) 时，为什么我的 Java Web 项目会引发错误

Question

我正在尝试使用 JPA，这是我的项目库的截图，我 很困惑，因为如果我不包含 EclipseLink-ModelGen(JPA 2.1)，我的项目编译成功并且运行正常，但是当我将它包含在任何一个中时我的项目库或处理器路径库会引发以下错误：

    warning: Supported source version 'RELEASE_6' from annotation processor 'org.eclipse.persistence.internal.jpa.modelgen.CanonicalModelProcessor' less than -source '12'
Note: Creating static metadata factory ...
1 warning


An annotation processor threw an uncaught exception.
Consult the following stack trace for details.
