i was facing the same problem but this answer worked for me give it a try.

Serializing CDT Project settings has encountered a null pointer exception exception

(from there:

Eclipse had added an extra node to my .cproject file, making it three in total. I removed this one, which was the one added by Eclipse and also the last one in the file.

<cconfiguration id="0.1230402123.1377291156">
    <storageModule buildSystemId="org.eclipse.cdt.managedbuilder.core.configurationDataProvider" id="0.1230402123.1377291156" moduleId="org.eclipse.cdt.core.settings" name="Debug">
        <externalSettings/>
        <extensions>
            <extension id="org.eclipse.cdt.core.VCErrorParser" point="org.eclipse.cdt.core.ErrorParser"/>
            <extension id="org.eclipse.cdt.core.GmakeErrorParser" point="org.eclipse.cdt.core.ErrorParser"/>
            <extension id="org.eclipse.cdt.core.CWDLocator" point="org.eclipse.cdt.core.ErrorParser"/>
            <extension id="org.eclipse.cdt.core.GCCErrorParser" point="org.eclipse.cdt.core.ErrorParser"/>
            <extension id="org.eclipse.cdt.core.GASErrorParser" point="org.eclipse.cdt.core.ErrorParser"/>
            <extension id="org.eclipse.cdt.core.GLDErrorParser" point="org.eclipse.cdt.core.ErrorParser"/>
        </extensions>
    </storageModule>
    <storageModule moduleId="org.eclipse.cdt.core.externalSettings"/>
</cconfiguration>

After removing that and restarting Eclipse everything was working again.
