Cannot create JPA Facet: "project facet jpt.jpa could not be found"
提问by AllieCat
I have a maven project in Eclipse Java EE IDE for Web Developers. But when I go enable JPA facet, I cannot choose JPA (there is no JPA option). Have I forgotten to include some dependency?
我在 Eclipse Java EE IDE 中有一个面向 Web 开发人员的 Maven 项目。但是当我启用 JPA facet 时，我不能选择 JPA（没有 JPA 选项）。我忘记包含一些依赖了吗？
I've installed the following Maven dependencies: eclipslink-2.5.-RC1.jar, javax.persistence-2.0.0.jar, and mysql-connector-java-5.1.9.jar.
我已经安装了以下 Maven 依赖项：eclipslink-2.5.-RC1.jar、javax.persistence-2.0.0.jar 和 mysql-connector-java-5.1.9.jar。
I get the following warning on my project:
我的项目收到以下警告：
Implementation of project facet jpt.jpa could not be found. Functionality will be limited.
找不到项目 facet jpt.jpa 的实现。功能将受到限制。
UPDATE: I have the Dali Java Persistence Tools installed.

The JPA facet is not dependent on what is in your pom.xml. Check to make sure you have these plugins installed (The ones highlighted in blue).
JPA 方面不依赖于 pom.xml 中的内容。检查以确保您安装了这些插件（以蓝色突出显示的插件）。

If they're missing you can find the plugin here: http://www.eclipse.org/webtools/dali/
如果他们丢失了你可以在这里找到插件：http: //www.eclipse.org/webtools/dali/
Hope this helps!
