我想以编程方式(从插件)更改 CDT 托管构建项目中单个文件的工具设置选项卡中杂项设置中的“其他标志”字段。 (有关如何使用 UI 进行此更改的屏幕截图和简要说明，请参阅 this Eclipse documentation page。)

注意:当我接近解决方案时，我现在已经更新了两次。但是，我没有在最后添加更新(就像我对较短的问题所做的那样)，而是修改了整个问题。如果看到导致我现在所在位置的面包屑有帮助，您可以阅读历史。

以下代码将导致写入 .cproject 文件的设置(我将在下面详细介绍)，但是当我打开文件的属性对话框时，单击 C/C++ Build->Settings 然后单击 Miscellaneous，更改不会出现在“其他标志”字段中(就像我使用对话框进行更改时那样)。

IWorkbench workbench = PlatformUI.getWorkbench();
IWorkbenchWindow workbenchwindow = workbench.getActiveWorkbenchWindow();
IWorkbenchPage workbenchpage = workbenchwindow.getActivePage();
IEditorPart editorpart = workbenchpage.getActiveEditor();
IEditorInput editorinput = editorpart.getEditorInput();
IResource file = ((IFileEditorInput)editorinput).getFile();
IProject project = file.getProject();
IManagedBuildInfo buildInfo = ManagedBuildManager.getBuildInfo(project);
IConfiguration[] configurations = buildInfo.getManagedProject().getConfigurations();
IConfiguration conf = configurations[0];
IFileInfo fileInfo = conf.createFileInfo(file.getFullPath());
ITool[] tools = fileInfo.getTools();
ITool tool = tools[0];
IOption option = tool.getOptionById("my.gnu.compiler.misc.other");
String oldOptionValue = option.getDefaultValue().toString();
String newOptionValue = oldOptionValue + " -eg";
ManagedBuildManager.setOption(fileInfo, tool, option, newOptionValue);
ManagedBuildManager.saveBuildInfo(project, true);

最佳答案

我怀疑您创建 IFileInfo 时可能存在问题。这是我们用于获取翻译单元的 IResourceInfo 以设置每个文件选项的代码:

protected IResourceInfo getResourceInfo(ITranslationUnit translationUnit, ICProjectDescription prjDescription) {

    ICProject cProject = translationUnit.getCProject();
    if (cProject != null) {
        ICConfigurationDescription cfgDescription = prjDescription.getActiveConfiguration();
        IConfiguration configuration = ManagedBuildManager.getConfigurationForDescription(cfgDescription);
        IPath projectPath = translationUnit.getResource().getProjectRelativePath(); 
        IResourceInfo ri = configuration.getResourceInfo(projectPath, true);

        if (ri == null) { 
            ri = configuration.createFileInfo(projectPath);
        }

        return ri;
    }

    return null;
}

IPath projectPath = translationUnit.getResource().getProjectRelativePath();
