我正在使用 NetBeans IDE 8.0.1(在 Win XP 上)。我最近将 EclipseLink 从 2.5.2 升级到 2.6.0 。更新已成功传播到所需位置。不存在与服务器相关的问题。它与 Java EE 应用程序配合得很好。
我已将以下 JAR 文件放置在 ${NetBeansHome}/java/modules/ext/eclipselink 下。
- eclipselink.jar
- javax.persistence_2.1.0.v201304241213.jar
- org.eclipse.persistence.jpa.jpql_2.6.0.v20150309-bf26070.jar
- org.eclipse.persistence.jpa.modelgen_2.6.0.v20150309-bf26070.jar
与更新之前一样。
进行这些更改后，我无法通过 ctrl + space 在任何地方获取 IDE 的智能。 ctrl + space 导致抛出以下异常。

上述 JAR 文件是否不包含 org.eclipse.persistence.jpa.jpql.tools.spi.IManagedTypeProvider 类？对于新版本的 EclipseLink，是否需要将其他一些 JAR 文件添加到 ${NetBeansHome}/java/modules/ext/eclipselink 中？本质上的修复是什么？
发现了一些错误报告，但它们已在各自的版本中修复。
<小时/>编辑:
org.eclipse.persistence.jpa.jpql.tools.spi.IManagedTypeProvider 类在 org.eclipse.persistence.jpa.jpql_2.6.0.v20150309-bf26070.jar 中可用，但根据 IDE 的日志，它似乎仍然引用 org.eclipse.persistence.jpa.jpql_2.5.2.v20140319-9ad6abd.jar 某处的旧 JAR 文件。在过去对 EclipseLink 的更新中没有发生这种情况。

最佳答案
org.eclipse.persistence.jpa.jpql.tools.spi.IManagedTypeProvider 位于
org.eclipse.persistence.jpa.jpql_2.6.1.qualifier.jar 在我的构建(来自 git 的 2.6.1 分支)中，但你已经在那里了。也许尝试在 NetBeans 中创建包含所有这些 JAR 的新库，并使用它来代替这个库。
不幸的是，我现在要去度假，但下周我可以仔细看看。我们可能会在 NetBeans 的 master 分支中将 EclipseLink 更新到 2.6.0。
