Eclipse在Java 9下显示空白错误信息

Question

我已安装Java 9插件。我的项目没有改变，但是当我尝试运行时，出现了这个错误： 如果您需要更多信息，请随时评论说明您没有足够的信息。

我的.log文件： https://pastebin.com/SQXZVcQk

- not my real name

---

哪个插件？来自哪里？这个项目之前能正常工作吗？您能否使用小型迷你项目重现此问题（例如，只有一个类和一个主函数）？您能否提供Eclipse错误日志文件的内容？如果删除插件，项目是否能够重新工作？目前状态下，仅凭这些信息是不足以帮助您的（除非已经遇到完全相同的问题的用户）。 - Zabuzard

它在Java 8中运行。 - not my real name

请查看工作区.metadata目录中的.log文件，以查看是否有更详细的消息。 - greg-449

你有那个插件的URL吗？ - nitind

@RayWu - 你如何配置项目的库？要使用哪个JDK，library.path等？ - Naman

Answer 1

根据我的理解，似乎是配置问题。可能会有两个原因/解决方法：

1. From the logs:

   Root exception:
   java.lang.ExceptionInInitializerError
       at com.jniwrapper.util.ProcessorInfo.b(SourceFile:95)
   Caused by: com.jniwrapper.LibraryNotFoundException: Cannot find JNIWrapper native library (jniwrap64.dll) in java.library.path:
   

   Eclipse is not able to configure the java.library.path properly, in which case you can try setting the VM argument using the following on the command line:

   -Djava.library.path="${workspace_loc:project}\lib;${env_var:PATH}"
   

   Check out How to add native library to "java.library.path" with Eclipse launch (instead of overriding it) for further details and platform specific solutions.

   && make sure you include the path to jdk-9 early access build that should ideally be a must for the plugin used based out of Java9.

2. Also, the log reads

   !ENTRY org.eclipse.ui 4 0 2017-08-27 09:22:31.358
   !MESSAGE Unhandled event loop exception
   !STACK 0
   java.lang.ArrayIndexOutOfBoundsException: -1
       at es.org.chemi.games.snake.ui.GameField.createGameField(GameField.java:217)
       at es.org.chemi.games.snake.ui.GameField$1.controlResized(GameField.java:99)
       at org.eclipse.swt.widgets.TypedListener.handleEvent(TypedListener.java:236)
       at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:86)
       at org.eclipse.swt.widgets.Display.sendEvent(Display.java:4428)
       at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1079)
   

   For the pertaining code, you might want to look into the implementation of createGameField at GameField.java:217. If this wasn't specifically occurring on previous java version for you then solving (1) should get rid of this or else you might want to give the solutions at Eclipse Bug: Unhandled event loop exception No more handles a try.

Answer 2

在Eclipse中遇到相同的错误时，我通过选择此选项来修复它，而不是默认选项（在快照中由红色箭头突出显示）。
