在Intellij中安装JPA

Question

我有Intellij Idea社区版，我在Scala编程。

我查看了以下内容：https://www.jetbrains.com/idea/help/enable-jpa-support.html然而，当我在Intellij中搜索名为JPA或Java EE的插件时，我什么也找不到。

知道为什么会这样吗？我没有搜索正确的插件吗？

对于IDEA解析符号，您需要添加相关的依赖项，就像添加任何其他依赖项一样。更好的选择是构建系统(SBT、Gradle或Maven)，或者如果您不使用其中任何一个，则直接使用IDEA项目：

Open the Project Structure dialog (e.g. Ctrl+Shift+Alt+S).
In the left-hand pane of the dialog, select Modules.
In the pane to the right, select the module of interest.
In the right-hand part of the dialog, on the Module page, select the Dependencies tab.
On the Dependencies tab, click add and select Library.
In the Choose Libraries dialog, click New Library.
If suggested, select:
    Java to create a Java library. Select the files and folders to be included in the library in the dialog that opens.
    From Maven to download a Java library from a public Maven repository. Specify the artifact to be downloaded and the associated settings in the Download Library from Maven Repository dialog.
In the Configure Library dialog:
    Specify the library name.
    Select the library level (global, project or module).
    Configure the library contents using add, iconLibExclude and delete.
    Click OK.
In the Choose Libraries dialog, click Add Selected.
If necessary, select the Export option and change the dependency scope.
Click OK in the Project Structure dialog. 

当然，这不会给您任何特殊的JPA支持。特别是，链接的问题讨论的是JPQL字符串中显示的错误，而不是注释本身。
