MyEclipse 8.0 升級至 8.5 無法啟動 No application id has been found

前兩天更新MyEclipse的SVN外掛程式的時候提示可以從8.0更新到8.5，於是很Happy地點了更新。

當時也準備關閉才更新的，也沒注意是否更新成功，今天再次啟動，提示Message並無法啟動......@_@

還好，無法啟動有log看：

應用程式錯誤，是一個RuntimeException，應用程式ID沒找到。

看第二行，eclipse.buildId=unknown

再看看其餘兩個Msg

com.genuitec.myeclipse.product8.ide找不到

ProvisioningEventBus無法獲得，中繼資料快取可以沒有清理好。

估想著就是Myeclipse.product8.ide找不到的問題，找找看吧。

在MyEclipse安裝根目錄有myeclipse.ini

-startup<br />../8.0GACommonDirectory/plugins/org.eclipse.equinox.launcher_1.0.201.R35x_v20090715.jar<br />--launcher.library<br />../8.0GACommonDirectory/plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.0.200.v20090519<br />-install<br />D:/MyEclipse/MyEclipse8.0GA<br />-vm<br />D:/MyEclipse/8.0GACommonDirectory/binary/com.sun.java.jdk.win32.x86_1.6.0.013/jre/bin/client/jvm.dll<br />-configuration<br />configuration<br />-vmargs<br />-Xmx512m<br />-XX:MaxPermSize=256m<br />-XX:ReservedCodeCacheSize=64m<br />

startup目標包有了

launcher.library的目標檔案夾也有了

jvm就不用看了，運行都運行不了怎麼來的錯誤提示（其實啟動包和運行lib也一樣，不過就是不放心，順便看一眼）

應該是配置的問題，就在安裝目錄下configuration檔案夾裡有個config.ini

com.genuitec.pulse.client.handshake.id 和 com.genuitec.pulse.client.credentials有關客戶資訊，這就用******注掉了，是有資訊的

很醒目的

eclipse.product=com.genuitec.myeclipse.product8.ide，立刻搜尋了一下。

咦？D盤MyEclipse的安裝目錄下有一個/8.0GACommonDirectory/plugins/com.genuitec.myeclipse.product8_8.0.0.me200911192201

但檔案夾名卻與設定檔中的eclipse.product的配置資訊不對應，其它地方就再也找不到product對應的檔案夾或者包了，看來應該有對應檔或者註冊資訊

再看看config.ini

org.eclipse.equinox.simpleconfigurator.configUrl對應了一個bundles.info

bundles.info？？？正好了....去找出來看看（這檔案太大，就不貼出來了）

用普通文檔編輯器就能開啟，正好是外掛程式名對應外掛程式包或檔案夾的設定檔。

在裡面搜尋com.genuitec.myeclipse.product8.ide，沒找到！

縮小搜尋範圍吧，找com.genuitec.myeclipse.product8，找到兩目標，但是卻不是product8，而是com.genuitec.myeclipse.product85

一想，哦！正好是8.0更新8.5之後啟動不起來的，看來自動升級沒把config給改過來。

這.....莫非是MyEclipse的Bug？

不管是不是Bug，還得靠MyEclipse做東西的，趕緊修改config.ini，把這倆參數給改了

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

儲存設定檔，重新啟動.....Bingo！體驗8.5去嘍！
