我正在使用Eclipse RCP（Kepler）编写Eclipse插件。一切都工作正常，直到昨晚突然我尝试测试我的插件时开始得到空指针异常。这是stacktrace的一个信息：

!ENTRY org.eclipse.ui.workbench 4 2 2013-08-24 08:36:17.616

要尝试找出可能发生的情况，我转到了插件的启动配置，然后点击“验证插件”并收到以下错误：

org.apache.xmlrpc
    Missing Constraint: Import-package: javax.xml.bind; version="0.0.0"

missing constraint

这可能是启动我的插件失败的原因吗？如果是这样，我该如何解决？

谢谢

您可以右键单击您的项目，转到Run as - ＆gt;运行配置和“插件”选项卡。在这里单击Add required plug-ins按钮，这将自动解决您的验证问题。

我必须在运行配置“Eclipse Application”中删除以下插件才能摆脱 xmlrpc警告：

org.apache.xmlrpc
org.eclipse.mylyn.bugzilla.core
org.eclipse.mylyn.bugzilla.ui
org.eclipse.mylyn.commons.xmlrpc

xmlrpc警告已经发生

  • Eclipse RCP，Oxygen的新下载
  • 使用“Hello World，Command”模板创建的新插件
  • Windows7

由于Oxygen，xmlrpc问题不会在控制台中出现，而是作为额外弹出窗口，我觉得这更令人讨厌和困惑。控制台显示以下附加输出：

这可能是启动我的插件失败的原因吗？

我猜不是。我的插件似乎没有受到这些警告的影响。

如果您手动更改插件选择，请注意并使用验证插件功能，以确保不会创建其他依赖项问题。

如果您安装了其他插件，您可能会看到更多警告，例如来自checkstyle：

!ENTRY org.eclipse.ui 2 0 2017-09-04 10:09:32.926
!MESSAGE Warnings while parsing the commands from the 'org.eclipse.ui.commands' and 'org.eclipse.ui.actionDefinitions' extension points.
!SUBENTRY 1 org.eclipse.ui 2 0 2017-09-04 10:09:32.926
!MESSAGE Commands should really have a category: plug-in='net.sf.eclipsecs.ui', id='CheckstylePlugin.PurgeCaches', categoryId='net.sf.eclipsecs'

!ENTRY org.eclipse.ui 2 0 2017-09-04 10:09:33.622
!MESSAGE Warnings while parsing the commands from the 'org.eclipse.ui.commands' and 'org.eclipse.ui.actionDefinitions' extension points.
!SUBENTRY 1 org.eclipse.ui 2 0 2017-09-04 10:09:33.622
!MESSAGE Commands should really have a category: plug-in='net.sf.eclipsecs.ui', id='CheckstylePlugin.PurgeCaches', categoryId='net.sf.eclipsecs'

=＆gt;这有点乱。因此，制作可以忽略的“默认”警告的副本可能是个好主意。然后，更容易看出警告是否与您自己的插件/最近的更改有关。

修改

我为checkstyle警告提交了一个错误，感谢Lars Koedderitzsch他们将在8.5.0版本中得到解决： https://sourceforge.net/p/eclipse-cs/bugs/428/

答案 2 :(得分：3)

如果您安装了EclipseLink 2.5.2，那么这是一个已知错误：https://bugs.eclipse.org/bugs/show_bug.cgi?id=456174

要修复此问题，请使用此更新站点更新到最新版本：http://download.eclipse.org/rt/eclipselink/updates/ 选择比2.5.2更新的版本

注意：我必须取消选中＆＃34;隐藏已安装的版本＆＃34;添加更新站点之后要安装的复选框，因为它似乎认为它已安装，但是当我取消选中该框时它显示该软件未安装。 安装新版本后，重新启动Eclipse，然后： 1.选择菜单：运行 - ＆gt;运行配置 2.单击按钮＆＃34;添加必需的捆绑包＆＃34;

之后一切正常

如果您正在尝试使用功能的RCP E4应用程序，请尝试将org.eclipse.e4.rcp添加到产品中的依赖项 - ＆gt;依赖关系窗格。并做“添加所需”。这解决了我的问题

尝试了其他方法之后：我做了：
