Eclipse Neon Tomcat插件下载错误

Question

我正在尝试下载Eclipse Neon中的tomcat插件。我是怎么下载的。但是当我尝试使用Windows为tomcat设置首选项时->Preferences->tomcat。它给了我下面的错误。我认为Eclipse中缺少一些插件激活器。如果你能看一下。

java.lang.ClassNotFoundException: An error occurred while automatically activating bundle org.uqbar.eclipse.tomcat.xt (706).

由：org.osgi.framework.BundleException引起：加载束激活器时出错。在org.eclipse.osgi.internal.framework.bundlecontextimpl.start(bundlecontextimpl.java:716)，在org.eclipse.osgi.internal.framework.equinoxbundle.java:932)，在org.eclipse.osgi.internal.framework.equinoxbundle.startworker0(equinoxbundle.java:932)，在Action.java:470)在org.eclipse.osgi.internal.hooks.eclipselazystarter.PostFindLocalClass（eclipselazystarter.java:107)...71更多原因是:java.lang.ClassNotFoundException:org.eclipse.core.internal.compatibility.pluginActivator在org.eclipse.osgi.internal.loader.bundleloader.findClassInternation(Bundleloader.java:372).Eclipse.osgi.internal.loader.bundleloader.FindClass（bundleloader.java：364）在org.eclipse.osgi.internal.framework.bundleContextimpl.loadBundleActivator（bundleContextimpl.java:757)在org.eclipse.osgi.internal.framework.bundleContextimpl.start（bundleContextimpl.java:711)...77更多

试图从eclipse market place下载它并没有帮助我。我从这里手动下载了插件，并安装在Eclipse中。对我有效。

谢谢
