Question

每当我尝试启动我的应用程序（基于Eclipse）时，它都会给我以下错误

java.lang.IllegalStateException: Cannot change the location once it is set.

它要求我提供工作空间。当我选择一个并做'确定'时。它只是关闭并抛出异常。我用Google搜索但没有太多文档。以前有人遇到过这个问题吗？

我搜索了一下，发现你需要在运行时配置中添加 @noDefault 。但它已经在我的.ini文件中了。问题如下 -

我的配置文件如下

--launcher.library
plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.100.v20110505
-showsplash
-showlocation
-data
–vm
/home/aniket/jdk1.7.0_11/bin
@noDefault
-vmargs
-Xms40m
-Xmx512m
-XX:MaxPermSize=256m
-Dosgi.requiredJavaVersion=1.5

我把它改成了

--launcher.library
plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.100.v20110505
-showsplash
-showlocation
-data
@noDefault
–vm
/home/aniket/jdk1.7.0_11/bin
-vmargs
-Xms40m
-Xmx512m
-XX:MaxPermSize=256m
-Dosgi.requiredJavaVersion=1.5

并且它有效。我的事情@noDefault必须在-showsplash -showlocation -data之后并且在指定

之前

–vm
/home/aniket/jdk1.7.0_11/bin

我知道这听起来有点傻，我不确定原因，但希望如果有人再次面对这种情况，这会有所帮助。
