Migrate from Eclipse 3.2 to 4.3 - RCP based application

Question

I try to migrate my plugin from eclipse 3.2 to eclipse 4.3. I face some major error when starting the plugin.

I got this error message:

The activator projectscheduler_final.Activator for bundle ProjectScheduler_Final is invalid

My OSGi Manifest looks like this:

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: ProjectScheduler_Final Plug-in
Bundle-SymbolicName: ProjectScheduler_Final; singleton:=true
Bundle-Version: 1.0.0
Bundle-Activator: projectscheduler_final.Activator
Bundle-Localization: plugin
Bundle-ClassPath: mysql-connector-java-5.1.18-bin.jar
Require-Bundle: org.eclipse.ui,
 org.eclipse.core.runtime,
 org.eclipse.ui.forms
Eclipse-LazyStart: true

And my pluginxml like this

<?xml version="1.0" encoding="UTF-8"?>
<?eclipse version="3.2"?>
<plugin>

   <extension
         id="application"
         point="org.eclipse.core.runtime.applications">

            default="false"
            icon="images/wand.png"
            id="CreateProject"
            name="Create project editor"/>
      <editor
            class="projectscheduler_final.ProjectSchedulerEditorCreateSubProject"
            default="false"
            icon="images/wand.png"
            id="CreateSubProject"
            name="Create subproject editor"/>
   </extension>
   <extension
         point="org.eclipse.ui.commands">
      <command
            id="ProjectScheduler Final.command1"
            name="ProjectScheduler Final.command1"/>
   </extension>

</plugin>

I tried a few tutorials from Vogella and co. but nothing cleared the error. I checked the Names of the application etc. everything seems to be in place. It would be nice if anybody would have some hint or a pointer where I should take a closer look at..

Answer 1

Firstly, you need to switch the core dependencies to the new target platform.

Go to -> -> Remove the , and then ! - > - >删除 ， 和然后再 ！

Secondly, remember to include all of your required plug-in from the window. 窗口中包含所有必需的插件。

Go there, go to , deselect , click , click , then and run it. ，取消选择 ，单击 ，单击 ，然后单击并运行它。

Many things have changed since 3.2, so if this still doesn't work, migrate the app manually. Start from scratch and copy class by class. Ocassionally see if the app starts.

我解决了问题，添加到MANIFEST.MF中的Bundle-ClassPath
