- Eclipse CDT是开发C/C++的
- 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++):
ENTRY org.eclipse.core.jobs 4 2 2011-07-19 02:27:53.796MESSAGE An internal error occurred during: "Launching tst".STACK 0java.lang.IllegalArgumentException at org.eclipse.osgi.framework.internal.core.PackageAdminImpl.getBundles(PackageAdminImpl.java:571) at org.eclipse.core.internal.runtime.InternalPlatform.getBundle(InternalPlatform.java:181) at org.eclipse.core.runtime.Platform.getBundle(Platform.java:1416) at org.springframework.ide.eclipse.core.BundleStateLocationVariableResolver.resolveValue(BundleStateLocationVariableResolver.java:32) at org.eclipse.core.internal.variables.DynamicVariable.getValue(DynamicVariable.java:54) at org.eclipse.cdt.internal.core.cdtvariables.EclipseVariablesVariableSupplier$EclipseVarMacro.loadValue(EclipseVariablesVariableSupplier.java:103) at org.eclipse.cdt.internal.core.cdtvariables.EclipseVariablesVariableSupplier$EclipseVarMacro.getStringValue(EclipseVariablesVariableSupplier.java:90) at org.eclipse.cdt.dsf.gdb.launching.LaunchUtils.getLaunchEnvironment(LaunchUtils.java:389) at org.eclipse.cdt.dsf.gdb.launching.LaunchUtils.getGDBVersion(LaunchUtils.java:281) at org.eclipse.cdt.dsf.gdb.launching.GdbLaunchDelegate.getGDBVersion(GdbLaunchDelegate.java:243) at org.eclipse.cdt.dsf.gdb.launching.GdbLaunchDelegate.launchDebugSession(GdbLaunchDelegate.java:129) at org.eclipse.cdt.dsf.gdb.launching.GdbLaunchDelegate.launchDebugger(GdbLaunchDelegate.java:83) at org.eclipse.cdt.dsf.gdb.launching.GdbLaunchDelegate.launch(GdbLaunchDelegate.java:72) at org.eclipse.debug.internal.core.LaunchConfiguration.launch(LaunchConfiguration.java:853) at org.eclipse.debug.internal.core.LaunchConfiguration.launch(LaunchConfiguration.java:702) at org.eclipse.debug.internal.ui.DebugUIPlugin.buildAndLaunch(DebugUIPlugin.java:924) at org.eclipse.debug.internal.ui.DebugUIPlugin$8.run(DebugUIPlugin.java:1128) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54)

- 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:
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

ubuntu使用也有2年了,很多开源的都是c/c++的,处于对性能和优秀软件的了解需要。
java主业,c/c++兼顾下。
