Q:

building osmand with "ant debug" gives error

I have checked out latest Osmand source code from here 
and followed all the steps from here
now i am trying to build apk through ant with command ant debug but it fails
i executed following commands :
myname@myname-VirtualBox:~/dev/osmand/android/OsmAnd$ ant -f build.xml
which gives output as
BUILD SUCCESSFUL

after when i try 
myname@myname-VirtualBox:~/dev/osmand/android/OsmAnd$ ant debug

it fails with following log in the end : 
-crunch:
   [crunch] Crunching PNG Files in source dir: /home/moonshooter/dev/osmand/android/OsmAnd/res
   [crunch] To destination dir: /home/moonshooter/dev/osmand/android/OsmAnd/bin/res
   [crunch] Crunched 0 PNG files to update cache

-package-resources:

/home/myname/dev/osmand/android/OsmAnd/build.xml:28: Missing attribute libraryRFileRefid

Total time: 18 seconds

the 27th and 28th lines in xml are 
<do-only-if-not-library elseText="Library project: do not package resources...">
                    <aapt executable="${aapt}" command="package" versioncode="${version.code}"versionname="${version.name}" debug="${build.is.packaging.debug}" manifest="${out.manifest.abs.file}"assets="${asset.absolute.dir}" androidjar="${project.target.android.jar}" apkfolder="${out.absolute.dir}"nocrunch="${build.packaging.nocrunch}" resourcefilename="${resource.package.file.name}"resourcefilter="${aapt.resource.filter}" libraryResFolderPathRefid="project.library.res.folder.path"libraryPackagesRefid="project.library.packages" previousBuildType="$`enter code here`{build.last.target}"buildType="${build.target}" ignoreAssets="${aapt.ignore.assets}">

and here is the whole file http://pastebin.com/Dv20iT8r
Can any one tell me what is the problem?

A:

Just need to add this property libraryRFileRefid="project.library.bin.r.file.path" in aapt tag
<do-only-if-not-library elseText="Library project: do not package resources...">
            <aapt executable="${aapt}" command="package" versioncode="${version.code}" versionname="${version.name}" debug="${build.is.packaging.debug}" manifest="${out.manifest.abs.file}" assets="${asset.absolute.dir}" androidjar="${project.target.android.jar}" apkfolder="${out.absolute.dir}" nocrunch="${build.packaging.nocrunch}" resourcefilename="${resource.package.file.name}" resourcefilter="${aapt.resource.filter}" libraryRFileRefid="project.library.bin.r.file.path" libraryResFolderPathRefid="project.library.res.folder.path" libraryPackagesRefid="project.library.packages" previousBuildType="${build.last.target}" buildType="${build.target}" ignoreAssets="${aapt.ignore.assets}">
