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gradle项目。

My Gradle项目（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时，控制台脱掉了这个丑陋的堆栈跟踪：

我曾经能够毫无问题地导入项目，但我现在收到此错误并且不知道原因。

非常感谢您的帮助:)。

更新： 工作区.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？

Answer 1

我也一直在与RAD9 / Gradle插件战斗，最后获得了成功的导入或简单的Java项目。

您是否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Sun / Oracle Java 7 JDK（不是JRE）？

enter image description here

我已经改变了很多东西试图让它工作，它可能需要比这个设置更多;然而，这个肯定是允许它工作的最终设置。请回复您的发现。如果它不适合你，我可以发布有关我的设置的其他信息（JAVA_HOME，GRADLE_HOME等）。

Answer 2

我收到一条关于Gradle的弹出消息说“”现有连接被远程主机强行关闭“，我的Elipse日志文件与上面相同。这对我来说很多次;这就是我做的。

在您的计算机上安装了JDK（例如：C：\ Program Files \ Java \ jdk1.7.0_71）。
在Window＆gt;下添加到Eclipse偏好＆gt; Java＆gt;已安装的JRE，使用上面相同的路径（例如：C：\ Program Files \ Java \ jdk1.7.0_71）。
（注意：您无需在此处将其作为当前活动路径进行检查，您只需要它已安装。）
- 单击“应用”。
设置Gradle＆gt;参数＆gt;工作区JRE到你刚刚添加的JRE（jdk一个）。
- 单击“应用”和“确定”。
重新启动Gradle构建。有一次我马上再次遇到同样的错误，但后来尝试了一些事情（干净的项目，双重检查JRE / Gradle配置等），并且构建启动并清除了我的错误。
