我将 Eclipse Juno 与 Java（Java build 1.7.0_05-b05 64bit）和 Scala-IDE 插件（用于 Eclipse 2.1.0.nightly-2_09-201207100348-f1d9c23 org.scala-ide.sdt.feature 的 Scala IDE。 feature.group scala-ide.org)。
以下是我对 Eclipse eclipse.ini 的自定义设置：
-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完成 Eclipse 时都会抛出 2 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.
和
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.
下面我的 scala-ide 日志显示：
[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

[Xlint:cantFindType]
有没有什么办法解决这一问题？
谢谢你。
更新 1：禁用代码推荐器后，我的 Slaca-Ide 日志中出现不同的错误：
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

但是 scala 代码完成现在可以正常工作
