TFS JAVA SDK 14.0.3 - How to fetch a remote file from server and make changes and check in again

[AnsarSamad]

I have a project in team foundation server named master-builds . the master-build folder has a xml file named build-main.xml

i want to fetch this files from server and make some changes in it (change the version number ) and check in again , how can i achieve it using TFS JAVA SDK 14.0.3 .

I tried the samples provided in the folder but not able to achieve

This is the code snippet to create workspace

public static Workspace createAndMapWorkspace(final TFSTeamProjectCollection tpc) {
        final String workspaceName = "SampleVCWorkspace" + System.currentTimeMillis(); //$NON-NLS-1$
        Workspace workspace = null;

        // Get the workspace
        workspace = tpc.getVersionControlClient().tryGetWorkspace(ConsoleSettings.MAPPING_LOCAL_PATH);

        // Create and map the workspace if it does not exist
        if (workspace == null) {
            workspace = tpc.getVersionControlClient().createWorkspace(
                null,
                workspaceName,
                "Sample workspace comment", //$NON-NLS-1$
                WorkspaceLocation.SERVER,
                null,
                WorkspacePermissionProfile.getPrivateProfile());

            // Map the workspace
            final WorkingFolder workingFolder = new WorkingFolder(
                ConsoleSettings.MAPPING_SERVER_PATH,
                LocalPath.canonicalize(ConsoleSettings.MAPPING_LOCAL_PATH));
            workspace.createWorkingFolder(workingFolder);
        }

        System.out.println("Workspace '" + workspaceName + "' now exists and is mapped"); //$NON-NLS-1$ //$NON-NLS-2$

        return workspace;
    }

public static void getLatest(final Workspace workspace) {
        final ItemSpec spec = new ItemSpec(ConsoleSettings.MAPPING_LOCAL_PATH, RecursionType.FULL);
        final GetRequest request = new GetRequest(spec, LatestVersionSpec.INSTANCE);
        workspace.get(request, GetOptions.NONE);
    }

    public static File addFile(final Workspace workspace) {

        // Create the file locally
        final File newFile = new File(ConsoleSettings.MAPPING_LOCAL_PATH, "SampleAppFile"); //$NON-NLS-1$
        writeFileContents(newFile, "", "UTF-8"); //$NON-NLS-1$ //$NON-NLS-2$

        // Pend an add
        // The encoding is passed as null and the add will detect the encoding
        // of the file
        workspace.pendAdd(new String[] {
            newFile.getAbsolutePath()
        }, false, ENCODING, LockLevel.UNCHANGED, GetOptions.NONE, PendChangesOptions.NONE);

        // Checkin the pending change
        final int cs = checkinPendingChanges(workspace, "Adding a sample file"); //$NON-NLS-1$

        System.out.println("Added file " + newFile.getAbsolutePath() + " in CS# " + cs); //$NON-NLS-1$ //$NON-NLS-2$

        return newFile;
    }

    public static void editFile(final Workspace workspace, final File file) {
        // Pend edit
        final ItemSpec fileSpec = new ItemSpec(file.getAbsolutePath(), RecursionType.NONE);
        workspace.pendEdit(
            new ItemSpec[] {
                fileSpec
        },
            LockLevel.UNCHANGED,
            ENCODING,

            GetOptions.NONE,
            PendChangesOptions.NONE);

        // Edit the file
        writeFileContents(file, "Edited this file at " + new Date().toString(), "UTF-8"); //$NON-NLS-1$ //$NON-NLS-2$

        // Checkin the pending change
        final int cs = checkinPendingChanges(workspace, "Editing the sample file"); //$NON-NLS-1$

        System.out.println("Edited file " + file.getAbsolutePath() + " in CS# " + cs); //$NON-NLS-1$ //$NON-NLS-2$
    }

These are my questions

I was able to successfully add a new file to the remote server , but am not able to edit an existing remote file .

If i call editFile followed by addFile method it will get updated , but i dont want to add enw file every time ,what i want is to fetch the latest version of the buils-main.xml file from server and make changes and do the check in.

Also after creating the workspace in local path i couldnt see it in that path , is that the correct behavior ?

Could anyone Please help me on this?
