包Y的Activator X无效,由ClassNotFoundException:X引起

Question

在eclipse中启动我的OSGi应用程序时,我收到以下错误:

org.osgi.framework.BundleException: The activator org.pathvisio.sbgn.SbgnPlugin for bundle org.pathvisio.sbgn is invalid

这似乎与以下问题相同: bundle的激活器无效

但是,无论我尝试什么,我都会遇到同样的错误.即使我将Activator类的名称更改为其他名称,它仍然使用旧的类名称给出了完全相同的错误.

显然eclipse正在缓存某些东西,但我不知道是什么或为什么.我已经尝试重新启动eclipse,并重建我工作区中的所有项目,但没有任何帮助.

这是我的MANIFEST.MF:

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: org.pathvisio.sbgn
Bundle-SymbolicName: org.pathvisio.sbgn
Bundle-Version: 1.0.0.qualifier
Bundle-Activator: org.pathvisio.sbgn.Activator
Bundle-ClassPath: lib/activation.jar,
 lib/google-collect-snapshot-20090211.jar,
 lib/jaxb-api.jar,
 lib/jaxb-impl.jar,
 lib/jaxb-xjc.jar,
 lib/jaxb1-impl.jar,
 lib/jsr173_1.0_api.jar,
 lib/org.sbgn.jar
Export-Package: org.pathvisio.sbgn
Require-Bundle: com.springsource.org.jdom;bundle-version="1.1.0",
 org.pathvisio.core;bundle-version="2.0.11",
 org.bridgedb;bundle-version="1.1.0",
 org.pathvisio.gui;bundle-version="2.0.11",
 org.pathvisio.desktop;bundle-version="2.0.11",
 org.bridgedb.bio;bundle-version="1.1.0"
Import-Package: org.osgi.framework;version="1.5.0"

正如您所看到的,我重命名了激活器类,但它仍然使用我之前指定的类名报告错误.

添加.,到Bundle-classpath并再次检查.它应该工作.
