[b]问题补充：[/b]
一加上-clean就能启动，但是感觉加上-clean是不是启动慢了呀，这样是治标不治本呀，有没有彻底的解决办法，这log记录能不能看出是那里出了问题，我好像感觉是RDT和flexbuilder的兼容性问题，不知道大家有没有什么好的解决办法？
[b]问题补充：[/b]
楼下的lovewhzlq哥们好像没明白我的问题呀，我的意思是说现在我的eclipse装了一些插件（应该说是N多），问题是现在启动的时候不加－clean启动不了，上面已经贴出了日志，就是说现在有什么办法不加这个-clean。加-clean感觉是治标不治本呀。
[b]问题补充：[/b]
要是Aptana的问题怎么解决呀哥们？
[b]问题补充：[/b]
哥们不知你说的启动不加载Aptana插件是什么意思呀?是不安装吗,还要是把他标用掉?如果不是的话应该如何设置呀.烦指教.
[b]问题补充：[/b]
试了还是不行呀，好你是装了RUBY的开发插件的问题.我看还是加-clean吧
如上面，把里面的Aptana打钩去掉就OK了
一般加-clean之后，第二次启动就没有什么问题，。。这问题的确很烦，在linux更严重，随着插件的增多，一些莫名的原因，eclipse稳定性会越来越差，安装之后最好查阅相关资料，保证兼容性。
如果还有问题，就删除workspace下的.metadata目录，再重新启动eclipse。
安装插件后在窗口— > 首选项 中看不到
① 把 eclipse\configuration\org.eclipse.update 删除掉。出现这种情况的原因是在你安装新的插件以前你启动过 eclipse ，在 org.eclipse.update 文件夹下记录了插件的历史更新情况，它只记忆了以前的插件更新情况，而你新安装的插件它并不记录，所以删除掉这个文件夹就可以解决这个问题了，不过删除掉这个文件夹后， eclipse 会重新扫描所有的插件，此时再重新启动 eclipse 时可能会比刚才稍微慢点。
② 创建一个 Eclipse 快捷启动方式，在目标栏中加入一个“ 空格— clean ”参数，注意不要把— clean 前面的空格漏掉。或者在菜单【开始】—【运行】中启动你的 eclipse 时加上— clean 参数，如我的可以在“运行”中输入： F:\hongjun\eclipse\eclipse.exe –clean
如果启动 eclipse 后找到你所安装的新插件后，在下次启动之前把参数 clean 去掉就可以了。
③ 如果 Eclipse 启动找不到插件的话，解决办法是在 eclipse\configuration 目录下的 config.ini 文件中加入一行 : osgi.checkConfiguration=true
这样它就会寻找并安装插件 , 找到插件后可以把该行注释掉 ( 去掉 ), 这样以后每次启动就不会因为寻找插件而显得慢了。
你只要安装了新插件就得-clean去启动，才能更新到这些插件啊，
这样安装插件也行
一、使用links方式安装eclipse插件
假设eclipse安装目录是D:\eclipse，待安装插件目录是D:\eclipseplugins。以lomboz，Sysdeo Eclipse Tomcat Launcher plugin和xmlbuddy为例说明如何使用links方式安装eclipse插件。
1、安装Lomboz
在D:\eclipseplugins中建立如下的目录结构：
D:\eclipseplugins\lomboz\eclipse
将lomboz安装文件解压到此目录中，这个目录将包含一个plugins目录，即目录结构是这样的：
D:\eclipseplugins\lomboz\eclipse\plugins
在D:\eclipse\links目录下新建文件，命名为lomboz.link，编辑此文件，加入如下内容并保存。
path = D:/eclipseplugins/lomboz
eclipse将会到指定的目录下去查找eclipse\features目录和eclipse\plugins目录，看是否有合法的功能部件和（或）插件。也就是说，目标目录必须包含一个 \eclipse 目录。如果找到，附加的功能部件和插件在运行期配置是将是可用的，如果链接文件是在工作区创建之后添加的，附加的功能部件和插件会作为新的配置变更来处理。
其它压缩文件解压后若已经包含eclipse\plugins目录，则不需要建立eclipse目录。
2、安装Sysdeo Eclipse Tomcat Launcher plugin
解压tomcatPluginV3.zip到目录D:\eclipseplugins\tomcatPlugin\eclipse\plugins目录下。
在D:\eclipse\links下新建文件，命名为tomcatPlugin.link，编辑此文件，加入如下内容并保存。
path = D:/eclipseplugins/tomcatPlugin
3、安装xmlbuddy
解压xmlbuddy安装文件到D:\eclipseplugins\xmlbuddy\eclipse\plugins目录下。
在D:\eclipse\links下新建文件，命名为xmlbuddy.link，编辑此文件，加入如下内容并保存。
path = D:/eclipseplugins/xmlbuddy
二、插件管理
启动eclipse，在菜单Help->Software Updates->Manage Configuration...下，启用或者禁用插件。
三、说明
1. 插件可以分别安装在多个自定义的目录中。
2. 一个自定义目录可以安装多个插件。
3. link文件的文件名及扩展名可以取任意名称，比如ddd.txt，myplugin都可以。
4. link文件中path=插件目录的path路径分隔要用\或是/
5. link文件可以有多行path=插件目录，对应多个自定义插件目录，每一行的path参数都将生效。
6. 在links目录也可以有多个link文件，每个link文件中的path参数都将生效。
7. 插件目录可以使用相对路径。
8. 可以在links目录中建立一个子目录，转移暂时不用的插件到此子目录中，加快eclipse启动。
9. 如果安装后看不到插件，把eclipse安装目录下的configuration/org.eclipse.update/目录整个删除，重启eclipse。
你这哪里拷过来的，在最新的eclipse，根本就不是这么回事。
Windows 下 eclipse 还是要稳定很多，linux下的 eclipse 问题不断，根本就没有办法使用。
我以前在博客描述这方面的问题。
有问题加了-clean也不会解决问题，删除~/workspace/.metadata目录和 eclipse下的configuration，重新拷贝一份新的configration。
有问题可以报到eclipse bug tracker上去，老外还是比较热情的。
偶也是遇到这个问题，事更新Aptana
Aptana捣鬼，看看Aptana支持的版本吧 哈哈
在Eclipse中把Aptana启动加载去掉就OK了，也就是启动不加载Aptana插件
Eclipse-Window-Preference-General-Start up and Shutdown
apanta要使用的话，专门下载一个官方集成版本，那东西的确问题多多。
哦，Ruby就不了解了，呵呵，工具嘛，能用就行！
