有osgi.ee包吗

Question

我一直在关注 Lars Vogel 的教程 [https://www.vogella.com/tutorials/EclipseTycho/article.html#google_vignette]。我目前陷入 RCP 插件项目的编译错误：

Software being installed: ... requires 'osgi.ee; (&(osgi.ee=JavaSE)(version=22))' but it could not be found

。关于这个问题有很多讨论，但我还没有看到解决方案。我想知道 Eclipse 版本：版本：2024-06 (4.32.0) 是否有解决上述问题的方法。大多数关于这个问题的讨论都超出了我的理解范围。以下是我的聚合器 pom 文件：

Answer 1

错误

requires 'osgi.ee; (&(osgi.ee=JavaSE)(version=22))

意味着插件/包需要 Java 22，因为在其

META-INF/MANIFEST.MF

中包含

Bundle-RequiredExecutionEnvironment: JavaSE-22

行，该行在您的 Maven/Tycho 构建中不可用：在您的 POM 中进行配置

target-platform-configuration

您指定了

<executionEnvironment>JavaSE-21</executionEnvironment>

，因此出现错误。

使用以下其中一个解决方案（我会推荐第一个解决方案，因为与 Java 21 相比，Java 22 没有提供长期支持）：

假设导致错误的插件/包是您的代码，
• 通过在其 META-INF/MANIFEST.MF 文件中将行

  Bundle-RequiredExecutionEnvironment: JavaSE-22

  更改为 Bundle-RequiredExecutionEnvironment: JavaSE-22，将插件/包从 Java 22 降级到 21
在 POM 中将
• <executionEnvironment>JavaSE-21</executionEnvironment>

   更改为 

  <executionEnvironment>JavaSE-22</executionEnvironment>（并确保使用 Java 22 或更高版本运行 Maven 构建）
在 POM 中将
• <executionEnvironment>JavaSE-21</executionEnvironment>

   更改为 

  <resolveWithExecutionEnvironmentConstraints>false</resolveWithExecutionEnvironmentConstraints>（并确保使用 Java 或更高版本运行 Maven 构建）
