Re: [ptp-dev] [Sync Projects] - Problems with providers
Hi

The code that you disabled converts the remote path into UNC format, which the CDT indexer
requires for indexing remote files. The code where the NPE occurs, however, only executes if the
path is in this format.

I would recommend using the debugger to walk through the "toURI" call to find out exactly what
causes the NPE.

Hi folks, when creating a sync project and changing the providers in order to locate the remote includes I got the following error:

This error is associated with this snippet of code from SyncGCCBuiltinSpecsDetector class (I removed the Windows part):

    List<ICLanguageSettingEntry> newEntries = new ArrayList<ICLanguageSettingEntry>();
        for (ICLanguageSettingEntry entry : entries) {
            if ((entry instanceof CIncludePathEntry) && ((entry.getFlags() & ICSettingEntry.VALUE_WORKSPACE_PATH) == 0)) {
                String oldPath = ((CIncludePathEntry) entry).getValue();
                String newPath = "//" + conn.getName() + oldPath; //$NON-NLS-1$
                ICLanguageSettingEntry newEntry = new CIncludePathEntry(newPath, entry.getFlags());
                newEntries.add(newEntry);
            } else {
                newEntries.add(entry);
            }
        }

Using the following snippet of code, the problem is gone, but the editor marks all the symbols as errors:

    List<ICLanguageSettingEntry> newEntries = new ArrayList<ICLanguageSettingEntry>();
        for (ICLanguageSettingEntry entry : entries) {
            if ((entry instanceof CIncludePathEntry) && ((entry.getFlags() & ICSettingEntry.VALUE_WORKSPACE_PATH) == 0)) {
                String oldPath = ((CIncludePathEntry) entry).getValue();
                //String newPath = "//" + conn.getName() + oldPath; //$NON-NLS-1$
                ICLanguageSettingEntry newEntry = new CIncludePathEntry(oldPath, entry.getFlags());
                newEntries.add(newEntry);
            } else {
                newEntries.add(entry);
            }
        }

Do you guys have any idea about the root of this problem ? I'm using the latest version of PTP.
