[Jenkins]Xamarin.Android.Common.targets(387,2): error :The specified path, or file name are too long

I'm trying to build the android solution from jenkins but i get the following error:

            _ResolveMonoAndroidSdks:

            Done Building Project "project.csproj" (Clean;Rebuild;SignAndroidPackage target(s)) -- FAILED.

This is the command used to build it: [msbuildpath]/msbuild.exe /t:Clean;Rebuild /p:JavaSdkDirectory="C:\Program Files\Java\jdk1.8.0_73" /p:AndroidNdkDirectory="C:\Program Files\Android\ndk\android-ndk" /t:SignAndroidPackage /p:Configuration=Release "project.csproj"

Notes:
1. From cmd and visual studio the app is compiling
2. when i run it from jenkins i also have to specify the Android NDK and javaSDK, otherwise in jenkins output i see "Android NDK: \" and java takes a different path ( Java SDK: C:\Program Files (x86)\Java\jdk1.7.0_71) even if my JAVA_HOME points to C:\Program Files\Java\jdk1.8.0_73\
