使用 Maven+Tycho 构建的 Eclipse 功能补丁

Question

我目前正在开发 Eclipse RCP 应用程序，它是使用 Maven v3.8.4 和 Tycho v2.6.0 构建的。一切都按预期工作，除了修补原始 Eclipse 功能的功能补丁 org.eclipse.platform.

这是功能 xml:

<feature
      id="com.eclipse.platform.patch"
      label="MAS Eclipse Platform Patch"
      version="0.0.1.qualifier"
      provider-name="MAS">

   <requires>
      <import feature="org.eclipse.platform" version="4.22.0.v20211124-1800" patch="true"/>
   </requires>

   <plugin
         id="org.eclipse.ui.navigator"
         download-size="0"
         install-size="0"
         version="0.0.0"
         unpack="false"/>

   <plugin
         id="org.eclipse.ui.ide"
         download-size="0"
         install-size="0"
         version="0.0.0"
         unpack="false"/>

   <plugin
         id="org.eclipse.ltk.ui.refactoring"
         download-size="0"
         install-size="0"
         version="0.0.0"
         unpack="false"/>

   <plugin
         id="org.eclipse.ui.navigator.resources"
         download-size="0"
         install-size="0"
         version="0.0.0"
         unpack="false"/>

</feature>

我必须将包含的插件版本设置为比原始插件“更新”的版本，如 Eclipse feature patch doesn't patch plugins 中所述。

但是，对于这些较新的版本，tycho 构建失败。

例如org.eclipse.ui.navigator原始版本是3.10.200.v20211009-1706。我在 MANIFEST.MF 中将其设置为 3.10.201.qualifier，在 pom.xml 中将其设置为 3.10.201-SNAPSHOT。

而第谷抱怨找不到 3.10.200.v20211009-1706 依赖项：

[ERROR] Cannot resolve project dependencies:
[ERROR]   Software being installed: mas.product 0.3.0.qualifier
[ERROR]   Missing requirement: org.eclipse.platform.feature.group 4.22.0.v20211124-1800 requires 'org.eclipse.equinox.p2.iu; org.eclipse.ui.navigator [3.10.200.v20211009-1706,3.10.200.v20211009-1706]' but it could not be found
[ERROR]   Cannot satisfy dependency: mas.product 0.3.0.qualifier depends on: org.eclipse.equinox.p2.iu; org.eclipse.platform.feature.group 0.0.0

我相信这一定与这个错误有关https://bugs.eclipse.org/bugs/show_bug.cgi?id=389698 我说得对吗？

任何解决方案甚至解决方法？谢谢！

好的，至少就我而言，升级到 tycho v0.2.7 可以解决问题。现在构建给出了一些关于依赖项的警告：

[WARNING] Following dependencies were not found by the slicer (you can disregard this if it is intentional):

但至少它不会失败！
