【问题描述】：

我有一个 Eclipse 插件，我想在不启动 Eclipse 的情况下从命令行运行它。我使用 OSGi 命令实现了这一点：

/Library/Java/JavaVirtualMachines/jdk1.7.0_60.jdk/Contents/Home/bin/java 
  -XstartOnFirstThread
  -Dosgi.requiredJavaVersion=1.5
  -XX:MaxPermSize=256m
  -Xms40m
  -Xmx512m
  -Declipse.ignoreApp=false
  -Dosgi.noShutdown=true    
  -Declipse.pde.launch=true
  -Dfile.encoding=MacRoman
  "-Xbootclasspath/p:/Users/aneeshmohan/Movies/eclipse Indigo/plugins/org.eclipse.jdt.debug_3.7.1.v20110802_r371/jdi.jar" 
  -classpath "/Users/aneeshmohan/Movies/eclipse Indigo/plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar"
  org.eclipse.equinox.launcher.Main
  -product org.talend.rcp.branding.tos.product 
  -data /Users/aneeshmohan/Desktop/MyWorkspace/../runtime-NewTalendCofiguration 
  -configuration file:/Users/aneeshmohan/Desktop/MyWorkspace/.metadata/.plugins/org.eclipse.pde.core/NewTalendCofiguration/ 
  -dev file:/Users/aneeshmohan/Desktop/MyWorkspace/.metadata/.plugins/org.eclipse.pde.core/NewTalendCofiguration/dev.properties 
  -os macosx 
  -ws cocoa 
  -arch x86_64 
  -nl en_US 
  -consoleLog 
  -console 
  -nosplash 
  --disableLoginDialog

这很好用，没有问题。我现在将我的 eclipse 和工作区复制到另一台机器上，并对路径进行了必要的更改，但是当我运行它时，我得到了 osgi 控制台，但最终得到了错误：

!MESSAGE Error loading bundle datas.  Recalculating cache.

谁能指出我正确的方向来解决这个错误？

【问题讨论】：

这是什么版本的 Eclipse？

【解决方案1】：

只是猜测：我看到您正在尝试使用 Windows 路径在 Mac 上盯着您的东西。您在路径中使用空格和引号。首先，我会尝试使用没有空格的“安全”路径。
