JSF-Java持久性API-Maven错误

我正试图通过JPA在我的JSFWeb应用程序中建立一个数据库连接。我仍然被这一点的复杂性吓坏了，但在阅读了一些教程之后，我似乎终于对它有了一点了解

我有以下课程：

实体类：

        } finally {

当我尝试运行这个程序（使用Maven和Tomcat作为服务器）时，我得到了以下错误消息，实际上并没有告诉我太多：

Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile (default-compile) on project gamerbud: Compilation failure
Failure executing javac, but could not parse the error:
javac: -endorseddirs requires an argument

To see the full stack trace of the errors, re-run Maven with the -e switch.
Re-run Maven using the -X switch to enable full debug logging.

For more information about the errors and possible solutions, please read the following articles:

未能在project gamerbud上执行目标org.apache.maven.plugins:maven编译器plugin:2.3.2:compile（默认编译）：编译失败
执行javac失败，但无法分析错误：

要查看错误的完整堆栈跟踪，请使用-e开关重新运行Maven。

我希望你们能支持我，我也会感谢每一个在JSF中使用JPA和MySQL数据库的教程或帮助

提前谢谢

您的POM文件似乎有问题。请将其添加到问题中。具体来说，maven编译器插件的配置似乎是错误的。在哪里定义了

${annowned.dir}

属性？乍一看，是缺少目录的问题。这可能是真的，但我不知道如何解决这个问题。自从自动生成后，我就没碰过pom。
