不尋常的eclipse插件問題

我有這個非常不尋常的問題。我開發了這個插件屬性頁。當我作爲Eclipse應用程序運行插件時，它完美地工作，但是當我將其導出並將其複製到eclipse/dropin文件夾時，我得到了ClassNotFoundException。不尋常的eclipse插件問題

我的MANIFEST.MF看起來是這樣的：

Manifest-Version: 1.0 
Bundle-ManifestVersion: 2 
Bundle-Name: SpectrumPlugin 
Bundle-SymbolicName: sinaut.spectrum.plugin; singleton:=true 
Bundle-Version: 1.0.0.qualifier 
Bundle-Activator: sinaut.spectrum.plugin.activator.SpectrumPluginActivator 
Require-Bundle: org.eclipse.core.runtime;bundle-version="3.4.0", 
org.eclipse.ui;bundle-version="3.4.2", 
org.eclipse.core.resources;bundle-version="3.4.2", 
org.eclipse.ui.console;bundle-version="3.3.1" 
Bundle-ActivationPolicy: lazy 
Bundle-RequiredExecutionEnvironment: JavaSE-1.6 
Bundle-ClassPath: JARs/sshfactory.jar, 
. 
Import-Package: org.eclipse.ui.console 
Export-Package: com.jscape.a, 
sinaut.spectrum.plugin.activator, 
sinaut.spectrum.plugin.ftp, 
sinaut.spectrum.plugin.preferences, 
sinaut.spectrum.plugin.remotebuild, 
sinaut.spectrum.plugin.ssh

plugin.xml中看起來是這樣的：

<plugin> 

    <extension 
     point="org.eclipse.ui.preferencePages"> 
     <page 
     id="BildPreferencePage" 
      name="Bild Preferences" 
      class="sinaut.spectrum.plugin.preferences.BildPreferencePage" 

      > 
     </page> 
    </extension> 
    <extension 
     point="org.eclipse.core.runtime.preferences"> 
     <initializer 
      class="sinaut.spectrum.plugin.preferences.PreferenceInitializer"> 
     </initializer> 
    </extension> 
    <extension 
     point="org.eclipse.ui.actionSets"> 
     <actionSet 
      id="sinaut.spectrum.plugin.RemoteBildActionSet" 
      label="RemoteBildActionSet" 
      visible="true"> 
     <menu 
       id="sinaut.spectrum.plugin.RemoteBuildMenu" 
       label="Remote Build Menu"> 
      <groupMarker 
        name="content"> 
      </groupMarker> 
      <separator 
        name="additions"> 
      </separator> 
     </menu> 
     <action 
       class="sinaut.spectrum.plugin.remotebuild.RemoteBuild" 
       icon="/icons/rb.gif" 
       id="sinaut.spectrum.plugin.RemoteBuild" 
       label="Remote Build" 
       state="true" 
       style="push" 
       toolbarPath="Normal/additions"> 
     </action> 
     </actionSet> 
    </extension> 

</plugin>

當我嘗試啓動該屬性頁"Unable to create the selected preference page.sinaut.spectrum.plugin.preferences.BildPreferencePage"我得到這個消息，與此堆棧跟蹤：

它一定是愚蠢的，但我只是不能看到它。如果有人能幫助我。我一直堅持這個小時。

啓動下面的說法

-console

日食然後，使用診斷，看看找到你的插件標識在OSGi控制檯像

ss sinaut.spectrum.plugin

最後爲什麼你的插件不能得到解決

diag <id found by ss command>

並嘗試啓動它以查看激活器中是否有任何錯誤

start <id>

當我執行ss sinaut.spectrum.plugin命令時，我收到以下消息：框架已啓動。 id State Bundle 沒有id：/ – Nezzit 2010-11-02 08:33:29

看起來你的插件沒有被OSGi安裝，怎麼樣嘗試eclipse.exe -clean或者在OSGi的控制檯上手動安裝插件。 – Kane 2010-11-02 09:08:07

是的，激活者有什麼問題......只是無法弄清楚什麼。我已經手動安裝插件，當我啓動它時，我得到BundleException：激活器... SpectrumPluginActivator捆綁sinautt.spectrum.plugin是無效的...我檢查build.properties文件和類本身，並且一切似乎都很好。非常感謝你。 – Nezzit 2010-11-02 09:49:34
