Eclipse CDT插件：将工具添加到Commandline

Question

目前我正在研究Eclipse CDT的插件。

我想要实现的目标：

在命令行之前添加一个工具（我们称之为cov）。

gcc -omain.o main.c

应该成为 cov gcc -omain.o main.c

我尝试编写一个自定义的BuildRunner，它扩展了ExternalBuildrunner，在调用外部运行程序之前修改了这些工具。我是通过编辑COmmandLinePattern

来做到这一点的

到目前为止，如果我不恢复旧的CommandLinePattern，它仍然有用。

是否有办法更新配置以使用修改后的工具，稍后在调用后再写回旧配置。

在修改之前，我备份了工具命令行模式，这样就不会出现问题了。我猜错了这里的更新步骤。

public class CovBuildRunner extends ExternalBuildRunner {

private final Set<String> VALUES;

public CovBuildRunner() {
    VALUES = new HashSet<String>();
    VALUES.add("gcc");
    VALUES.add("g++");
}

@Override
public boolean invokeBuild(int kind, IProject project,
        IConfiguration configuration, IBuilder builder, IConsole console,
        IMarkerGenerator markerGenerator,
        IncrementalProjectBuilder projectBuilder, IProgressMonitor monitor)
        throws CoreException {
    Map<ITool, String> cmdPatternBackup = new HashMap<>();
    for (ITool tool : configuration.getTools()) {
        if (cmdPatternBackup.containsKey(tool)) {
            System.out.println("ERROR! TOOL ALREADY MODIFIED!");
        } else if (this.supports(tool)) {
            cmdPatternBackup.put(tool, tool.getCommandLinePattern());
            tool.setCommandLinePattern("cov " + tool.getCommandLinePattern());
            System.out.println(
                    configuration.getToolCommand(tool));
        }
    }
    configuration.getToolChain().set;
    boolean success = invokeExternalBuild(kind, project, configuration, builder, console, markerGenerator, projectBuilder, monitor);
    for (ITool tool : cmdPatternBackup.keySet()) {
        try {
            Thread.sleep(10000);
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        System.out.println("Setting back " + tool.getName() + "\n" + tool.getCommandLinePattern());
        tool.setCommandLinePattern(cmdPatternBackup.get(tool));
    }
    return success;
}

private boolean supports(ITool tool) {
    String command = tool.getToolCommand();
    return VALUES.contains(command);
}

}
