答案 0 :(得分：0)

这个问题的主题最好是： 来自org.jboss.ide.eclipse.archives.core.WorkspaceChangeListener的 NullPointerException（从插件调用代码时出现问题：“org.eclipse.core.resources”。

我正在使用：

  • JBoss Developer Studio（核心功能）7.0.1.GA-v20130930-2238-B7 com.jboss.jbds.product.feature.feature.group JBoss by Red Hat
    • （请参阅Eclipse-＆gt;帮助 - ＆gt;关于 - ＆gt;安装详情 - ＆gt;已安装的软件）
  • JBossTools Archives Core Plugin 3.4.100.Final-v20130717-0846-B106（org.jboss.ide.eclipse.archives.core）
    • （请参阅Eclipse-＆gt;帮助 - ＆gt;关于 - ＆gt;安装详情 - ＆gt;插件）

我没有找到最终答案，但有些指出要稍微缩小原因（如果不需要，在Eclipse中卸载JBOSS开发工具可能会解决它）：

  • 已经修复了类似的错误，但没有进一步解释可能导致它的原因：

  • 2008：这里我们还有一些（与插件代码相关的）开发人员提示：https://issues.jboss.org/browse/JBIDE-2746?page=com.atlassian.jira.plugin.system.issuetabpanels:changehistory-tabpanel&_sscc=t

    • 忘记设置组件

    • 忘了关闭

    • 当资源=工作区根

      • 时的NPE

  • 我的一些相关例外（似乎不是原因，而是“问题触发器”）：
