Eclipse启动时弹出空白提示框(Widget disposed too early)

eclipse linuxeclipse.initganymedeWidget disposed too early 
阅读更多

想使用eclipse来尝试开发Android, 结果eclipse classic版本在ubuntu下竟然挂了，找了许久才找到solution, 做个标记。

 

系统环境：

        ubuntu 10.04 (从9.10中更新而来的)

        eclipse-java-ganymede-linux-gtk


现象：
      启动eclipse classic版本，最后只弹一个空白提示框，无法 [关闭] 或 [确定]

出错日志分析：

      查看工作空间下的".metadata/.log"，报错信息主要有以下两方面：


            java.lang.RuntimeException: Widget disposed too early!


            org.eclipse.swt.SWTError: XPCOM error -2147467262

分析：

      以前运行过eclipse-jee版本，并无出现此问题，所以多数情况与classic版本带的swt相关。

 

      尝试修改eclipse用一个启动脚本启动(eclipse-win.sh)，使之以window窗体模式启动，但无效。         

 

#!/bin/sh
export GDK_NATIVE_WINDOWS=1
/home/lsm/web/eclipse/eclipse
(以上脚本可以解决eclipse中某些确认按钮无法按下去的问题
)

 


      借鉴网上的解决方案：

            https://www-304.ibm.com/support/docview.wss?uid=swg21265773 （英文）
            http://blog.sina.com.cn/s/blog_627399080100qnaj.html  （简单）
            http://sunshineyao.iteye.com/blog/836985

            https://bugzilla.redhat.com/show_bug.cgi?id=483832

      主要是因为firefox修改了xulrunner环境导致eclipse找不到xulrunner环境从而不能加载内置窗口。

解决方法（最简单)：
       在eclipse.ini的vmargs后面加上
              -Dorg.eclipse.swt.browser.XULRunnerPath=/usr/lib/xulrunner 

如下示例：
-showsplash
org.eclipse.platform
-framework
plugins/org.eclipse.osgi_3.4.0.v20080605-1900.jar
-vmargs
-Dorg.eclipse.swt.browser.XULRunnerPath=/usr/lib/xulrunner
-Dosgi.requiredJavaVersion=1.5
-Xms40m
-Xmx256m
-XX:MaxPermSize=256m

 

       经尝试，当第一次能启动后，eclipse.ini部分配置会写在工作工间的".metadata"里。

       即使你删除了-Dorg.eclipse.swt.browser.XULRunnerPath=/usr/lib/xulrunner，eclipse仍然可以启动。

 

其他解决方法不深入研究。

 

 

总结：

      Eclipse不能启动，应当尝试去查看metadata里的日志信息，获取最直接的出错原因。
