我正在使用Java（Java build 1.7.0_05-b05 64bit）和Scala-IDE插件（Scala IDE for Eclipse 2.1.0.nightly-2_09-201207100348-f1d9c23 org.scala-ide.sdt.feature.feature.group scala-ide.org）的Eclipse Juno。
以下是我自定义的Eclipse eclipse.ini设置：
-vmargs
-Dosgi.requiredJavaVersion=1.7
-Dhelp.lucene.tokenizer=standard
-Xss8m
-Xms256m
-Xmx1536m
-XX:PermSize=64m
-server
-Xverify:none
-XX:+UnlockExperimentalVMOptions
-XX:+UseG1GC
-XX:MaxGCPauseMillis=50
-XX:+DoEscapeAnalysis
-XX:+UseCompressedOops
每次我尝试使用代码自动完成功能，Eclipse都会弹出两个错误窗口：
The 'Code Recommenders Calls Proposals' proposal computer from
the 'org.eclipse.recommenders.completion.rcp.calls' plug-in did
not complete normally.
The extension has thrown a runtime exception.
并且
The 'Code Recommenders Overrides Proposals' proposal computer from
the 'org.eclipse.recommenders.completion.rcp.overrides' plug-in did
not complete normally.
The extension has thrown a runtime exception.
我的Scala-IDE日志如下所示：
[Xlint:cantFindType]
2012-07-10 15:37:29,404 ERROR [main] - System.err -
[org.eclipse.jdt.launching] error can't determine modifiers of missing type
org.eclipse.pde.internal.ui.wizards.imports.PluginImportHelper
when weaving type org.eclipse.jdt.launching.JavaRuntime
when weaving classes
when weaving
[Xlint:cantFindType]
有没有办法修复这个问题？
谢谢。
更新1： 在禁用代码推荐后，我在我的Slaca-Ide日志中得到了不同的错误：
2012-07-10 16:10:24,342 ERROR [main] - System.err - [org.eclipse.jdt.debug.ui]
error can't determine modifiers of missing type
org.eclipse.pde.internal.ui.wizards.imports.PluginImportHelper
when weaving type org.eclipse.jdt.internal.debug.ui.actions.ToggleBreakpointAdapter
when weaving classes
when weaving
[Xlint:cantFindType]
但是现在Scala代码补全已经可以正常工作了。
