[Fixed Eclipse CDT]可正常运行,无法调试

1.Eclipse CDT是开发C/C++的
2.现象:
直接使用Eclipse IDE for C/C++ Developers可正常编写运行、调试c/c++
使用Eclipse for RCP RAP,已集成了MyEclipse,再安装Eclipse CDT插件时,只能正常运行,但是无法调试程序,运行调试时报异常(貌似是spring ide插件工具和CDT有冲突,毕竟是java开发环境来开发c/c++):
Java代码

解决:
创建插件项目,引入CDT依赖包,org.eclipse.cdt.dsf.gdb.launching.LaunchUtils.getLaunchEnvironment(LaunchUtils.java:389)处设置断点,观察问题现象
通过2种不同的目标插件平台:a) 集成了MyEclipse的eclipse RCP 和 b) Eclipse IDE for C/C++ Developers,对比发现他们获取到的env内容有差别,关键在bundle_loc、bundle_state_loc、bundle_version这三个,这三个在org.springframework.ide.eclipse.core/META-INF/MANIFEST.MF中参考代码
因为对CDT和Spring IDE插件都不了解,治标修复LaunchUtils代码,getLaunchEnvironmen方法中的envMap.put(var.getName(), var.getStringValue());替换为:
Java代码 
try { 
    envMap.put(var.getName(), var.getStringValue()); 
} catch (IllegalArgumentException e) { 
    if (var.getName() == null || !var.getName().startsWith("bundle_")) throw e; 
    ResourcesPlugin.getPlugin().getLog().log(new Status(IStatus.INFO, GdbPlugin.PLUGIN_ID, "ignore env variable [" + var.getName() + "] fetch error!", e)); 

 
替换包org.eclipse.cdt.dsf.gdb_3.0.0.201102110609.jar中的二进制代码即可
附件说明:
zip包是LaunchUtils.class代码
org.eclipse.cdt.dsf.gdb_3.0.0.201102110609.jar是修复后的包
