eclipse - gradle ide eclipse plugin import gradle project build model 导致 UnsatisfiedLinkError: net

Question

我正在运行 Rational Application Developer v9.0 并尝试使用 Gradle IDE eclipse 插件 (v3.4.0) 导入一个 gradle 项目。

我的 Gradle 项目（一个嵌套的多项目构建）在命令行中正确构建，但是当我尝试导入它并单击build model控制台时，会脱口而出这个丑陋的堆栈跟踪：

我以前可以毫无问题地导入项目，但我现在收到此错误，不知道为什么。

非常感谢您的帮助：）。

更新：工作区的 .metadata 目录中的日志文件显示更详细的日志消息，有什么想法吗？

我也一直在进行同样的 RAD9/Gradle 插件之战，最终成功导入或获得了一个简单的 Java 项目。

您可以尝试在某处安装 Sun/Oracle JDK 7，确保 Gradle 本身已配置为使用它，然后进入 RAD Preferences/Gradle/Arguments 并将 Java Home 设置为 Workspace JRE：-指向您的 Sun/Oracle Java 7 JDK （不是JRE）？

在此处输入图像描述

我已经更改了很多东西以尝试使其正常工作，它可能需要的不仅仅是此设置；但是，这无疑是使其工作的最终设置。请发回您的发现。如果它对您不起作用，我可以发布有关我的设置的附加信息（JAVA_HOME、GRADLE_HOME 等）。

我收到一条关于 Gradle 的弹出消息，指出“现有连接被远程主机强行关闭”，我的 Elipse 日志文件与上述相同。这对我多次有用；这就是我所做的。

在您的计算机上安装 JDK（例如：C:\Program Files\Java\jdk1.7.0_71）。
在 Window > Preferences > Java > Installed JREs 下添加到 Eclipse，使用与上面相同的路径（例如：C:\Program Files\Java\jdk1.7.0_71）。
（注意：您不需要在此处将其检查为当前活动的，您只需要安装它即可。）
- 单击应用。
将 Gradle > Arguments > Workspace JRE 设置为您刚刚添加的 JRE（jdk 之一）。
- 单击应用和确定。
重新启动 Gradle 构建。有一次我马上又遇到了同样的错误，但随后尝试了一些东西（清理项目、仔细检查 JRE/Gradle 配置等），构建开始并清除了我的错误。
