Myeclipse Eclipse OSGI Java IDE

解决MyEclipse 8.0 升级至 8.5 无法启动的问题

解决办法：

修改 config.ini，把这俩参数给改了

eclipse.product=com.genuitec.myeclipse.product8.ide
osgi.splashPath=platform\:/base/plugins/com.genuitec.myeclipse.product8

改为：

eclipse.product=com.genuitec.myeclipse.product85.ide
osgi.splashPath=platform\:/base/plugins/com.genuitec.myeclipse.product85

OK!!

前两天更新MyEclipse的SVN插件的时候提示可以从8.0更新到8.5，于是很Happy地点了更新。

当时也准备关闭才更新的，也没注意是否更新成功，今天再次启动，提示Message并无法启动......@_@

还好，无法启动有log看：

应用程序错误，是一个RuntimeException，应用程序ID没找到。

看第二行，eclipse.buildId=unknown

再看看其余两个Msg

com.genuitec.myeclipse.product8.ide找不到

ProvisioningEventBus无法获得，元数据缓存可以没有清理好。

估想着就是Myeclipse.product8.ide找不到的问题，找找看吧。

在MyEclipse安装根目录有myeclipse.ini
view plaincopy to clipboardprint?

 1. -startup
 2. ../8.0GACommonDirectory/plugins/org.eclipse.equinox.launcher_1.0.201.R35x_v20090715.jar
 3. --launcher.library
 4. ../8.0GACommonDirectory/plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.0.200.v20090519
 5. -install

startup目标包有了

launcher.library的目标文件夹也有了

jvm就不用看了，运行都运行不了怎么来的错误提示（其实启动包和运行lib也一样，不过就是不放心，顺便看一眼）

应该是配置的问题，就在安装目录下configuration文件夹里有个config.ini

com.genuitec.pulse.client.handshake.id 和 com.genuitec.pulse.client.credentials有关客户信息，这就用******注掉了，是有信息的

很醒目的

eclipse.product=com.genuitec.myeclipse.product8.ide，立刻搜索了一下。

咦？D盘MyEclipse的安装目录下有一个\8.0GACommonDirectory\plugins \com.genuitec.myeclipse.product8_8.0.0.me200911192201

但文件夹名却与配置文件中的eclipse.product的配置信息不对应，其它地方就再也找不到product对应的文件夹或者包了，看来应该有映射文件或者注册信息

再看看config.ini

org.eclipse.equinox.simpleconfigurator.configUrl对应了一个bundles.info

bundles.info？？？正好了....去找出来看看（这文件太大，就不贴出来了）

用普通文档编辑器就能打开，正好是插件名对应插件包或文件夹的配置文件。

在里面搜索com.genuitec.myeclipse.product8.ide，没找到！

缩小搜索范围吧，找com.genuitec.myeclipse.product8，找到两目标，但是却不是product8，而是 com.genuitec.myeclipse.product85

一想，哦！正好是8.0更新8.5之后启动不起来的，看来自动升级没把config给改过来。

这.....莫非是MyEclipse的Bug？

不管是不是Bug，还得靠MyEclipse做东西的，赶紧修改config.ini，把这俩参数给改了

eclipse.product=com.genuitec.myeclipse.product85.ide
osgi.splashPath=platform\:/base/plugins/com.genuitec.myeclipse.product85

保存配置文件，重新启动.....Bingo！体验8.5去喽！
