java.lang.ArrayStoreException：org.eclipse.e4.ui.model.application.ui.menu.impl.MenuContributionImpl

Question

我正在将一个menuContribution添加到eclipse插件中，我收到上面的错误消息。以下是 fragment.e4xmi

在google搜索和浏览stackoveflow for java.lang.ArrayStoreException 相关问题后，我找不到任何有用的信息。我将非常感谢任何指出这一点。

Answer 1

此：

<fragments xsi:type="fragment:StringModelFragment" xmi:id="_8OBJMEZTEeehrvUiei9LJA" featurename="handlers" parentElementId="org.eclipse.e4.legacy.ide.application">
    <elements xsi:type="menu:MenuContribution" xmi:id="_JcJ-cEZUEeehrvUiei9LJA" elementId="com.bodastage.e4.clock.ui.menucontribution.0" parentId="help">
      <children xsi:type="menu:HandledMenuItem" xmi:id="_OSQxwEZUEeehrvUiei9LJA" elementId="com.bodastage.e4.clock.ui.handledmenuitem.Hello" label="Hello" iconURI="platform:/plugin/com.bodastage.e4.clock.ui/icons/sample.gif" command="_4tuLgEOQEeedq-IevvWAag"/>
    </elements>
</fragments>

正在尝试添加菜单贡献到处理程序 featurename="handlers"列表，这是不允许的。您需要更改此选项以将菜单项添加为现有菜单的children。

Answer 2

我通过将menuContributions的featurename更改为 menuContributions 来解决了这个问题。下面是一个显示变化的片段。

  <fragments xsi:type="fragment:StringModelFragment" xmi:id="_hiF-4EawEeehrvUiei9LJA" featurename="menuContributions" parentElementId="org.eclipse.e4.legacy.ide.application">
    <elements xsi:type="menu:MenuContribution" xmi:id="_CnpqgEaxEeehrvUiei9LJA" elementId="com.bodastage.e4.clock.ui.menucontribution.0" parentId="help">
      <children xsi:type="menu:HandledMenuItem" xmi:id="_JsBsMEaxEeehrvUiei9LJA" elementId="com.bodastage.e4.clock.ui.handledmenuitem.Hello" label="Hello" iconURI="platform:/plugin/com.bodastage.e4.clock.ui/icons/sample.gif" command="_4tuLgEOQEeedq-IevvWAag"/>
    </elements>
  </fragments>
