启动插件失败,缺少约束javax.xml.bind

Question

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.这是堆栈跟踪的一个snippit:

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

为了试图弄清楚可能会发生什么,我去了我的插件的启动配置并单击"验证插件"并得到以下错误:

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

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

Answer 1

您可以右键单击项目,转到"运行方式" - >"运行配置"和"插件"选项卡.点击Add add plug-ins按钮,这将自动解决您的验证问题.

Answer 2

我不得不在运行配置"Eclipse Application"中删除以下插件以摆脱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

• 全新下载Eclipse RCP,Oxygen
• 使用"Hello World,Command"模板创建的新插件
• Windows 7的

由于Oxygen xmlrpc问题不会出现在控制台中,而是作为一个额外的弹出窗口,我发现它更令人烦恼和困惑.控制台显示以下附加输出:

 SLF4J: Class path contains multiple SLF4J bindings.
    SLF4J: Found binding in [bundleresource://555.fwk1347294617:1/org/slf4j/impl/StaticLoggerBinder.class]

    EGit might behave differently since they see different configuration options.
    This warning can be switched off on the Team > Git > Confirmations and Warnings preference page. 

这可能是启动我的插件失败的原因吗？

我猜不会.我的插件似乎没有受到这些警告的影响.

• 该git的警告可以在Eclipse团队的喜好被禁用,因为它本身的警告提示.

• 该SLF4J警告可以通过删除插件来解决ch.qos.logback.slf4j,也见多SLF4J绑定在Eclipse RCP插件

如果您手动更改插件选择,请小心并使用验证插件功能,以确保您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的警告:

!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.

!MESSAGE Commands should really have a category: plug-in='net.sf.eclipsecs.ui', id='CheckstylePlugin.PurgeCaches', categoryId='net.sf.eclipsecs'

=>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.

编辑

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/

尝试不同的东西后：我做了：

帮助>安装新软件

并添加了此存储库： http://download.eclipse.org/tools/orbit/downloads/drops/R20190226160451/ 从轨道获取的存储库： https: //download.eclipse.org/tools/orbit/downloads/drops/R20190226160451/

选择与.javax、xml流相关的

这对我有用。Eclipse 建模工具版本：2019-03 (4.11.0) win 10
