使用Tycho构建的Eclipse RCP产品启动失败问题求助

问题描述 #

我有一个使用Maven-Tycho构建的Eclipse RCP项目。此前通过Maven构建后，该项目可在任何安装了JavaSE运行环境的主机上正常启动。但在某次更新（不清楚具体是哪些更新）后，生成的归档包在所有Windows主机上均无法启动，报错日志如下：

我的机器上已安装JavaSE 11、14和15三个版本的运行环境，且该项目可在Eclipse中正常启动。我已尝试重装不同版本的Java运行环境，但问题仍未解决，恳请提供排查线索。

排查线索 #

• 检查启动脚本的Java版本指定：打开项目生成的Windows启动脚本（.bat文件），确认是否通过JAVA_HOME或-vm参数指定了Java 11的路径，避免系统默认使用低版本或不兼容的JDK。
• 验证Maven构建的Java环境：执行mvn -v查看Maven当前使用的JDK版本，确保构建过程基于Java 11（Eclipse中的运行环境和Maven构建环境可能不一致）。
• 检查Tycho配置的Java兼容性：查看项目pom.xml或Tycho目标平台配置，确认osgi.ee相关配置是否明确要求Java 11，比如<require-osgi-ee>节点的设置是否正确。
• 核对目标平台的组件版本：报错中涉及的org.eclipse.equinox.simpleconfigurator版本为1.4.100.v20220620-1617，对比之前正常构建的版本，确认是否因组件更新导致Java版本要求提升，必要时回退到兼容版本。
• 检查config.ini配置：查看归档包中configuration/config.ini文件，确认是否存在org.eclipse.osgi.requiredJavaVersion=11配置项，若缺失则添加，若存在则验证值是否正确。
• 确认Windows系统的默认Java版本：打开命令行执行java -version，确认当前系统默认的Java版本是否为11，若不是则调整系统PATH优先级，或在启动脚本中强制指定Java 11路径。
• 对比构建产物的依赖差异：将当前报错的归档包与之前正常工作的版本对比，检查plugins目录下的依赖组件（尤其是Equinox相关）是否有版本变更或缺失，确保所有依赖与Java 11兼容。
