Failed repacking when building android game

Since i'm desperate and i've obtain nothing googling the problem, i have to ask what should i do about this:

 Error building Player: CommandInvokationFailure: Failed to re-package resources. See the Console for details.

    Package the android resources.  It will read assets and resources that are
    supplied with the -M -A -S or raw-files-dir arguments.  The -J -P -F and -R
    options control which files are output.
 
  aapt r[emove] [-v] file.{zip,jar,apk} file1 [file2 ...]
    Delete specified files from Zip-compatible archive.
 
  aapt a[dd] [-v] file.{zip,jar,apk} file1 [file2 ...]
    Add specified files to Zip-compatible archive.
 
  aapt c[runch] [-v] -S resource-sources ... -C output-folder ...
    Do PNG preprocessing on one or several resource folders
    and store the results in the output folder.
 
  aapt s[ingleCrunch] [-v] -i input-file -o outputfile
    Do PNG preprocessing on a single file.
 
  aapt v[ersion]
    Print program version.
 
  Modifiers:
    -a  print Android-specific data (resources, manifest) when listing
    -c  specify which configurations to include.  The default is all
        configurations.  The value of the parameter should be a comma
        separated list of configuration values.  Locales should be specified
        as either a language or language-region pair.  Some examples:
             en
             port,en
             port,land,en_US
    -d  one or more device assets to include, separated by commas
    -f  force overwrite of existing files
    -g  specify a pixel tolerance to force images to grayscale, default 0
    -j  specify a jar or zip file containing classes to include
    -k  junk path of file(s) added
    -m  make package directories under location specified by -J
    -u  update existing packages (add new, replace older, remove deleted files)
    -v  verbose output
    -x  create extending (non-application) resource IDs
    -z  require localization of resource attributes marked with
        localization="suggested"
    -A  additional directory in which to find raw asset files
    -G  A file to output proguard options into.
    -F  specify the apk file to output
    -I  add an existing package to base include set
    -J  specify where to output R.java resource constant definitions
    -M  specify full path to AndroidManifest.xml to include in zip
    -P  specify where to output public resource definitions
    -S  directory in which to find resources.  Multiple directories will be scanned
        and the first match found (left to right) will take precedence.
    -0  specifies an additional extension for which such files will not
        be stored compressed in the .apk.  An empty string means to not
        compress any files at all.
    --debug-mode
        inserts android:debuggable="true" in to the application node of the
        manifest, making the application debuggable even on production devices.
    --include-meta-data
        when used with "dump badging" also includes meta-data tags.
    --pseudo-localize
        generate resources for pseudo-locales (en-XA and ar-XB).
    --min-sdk-version
        inserts android:minSdkVersion in to manifest.  If the version is 7 or
        higher, the default encoding for resources will be in UTF-8.
    --target-sdk-version
        inserts android:targetSdkVersion in to manifest.
    --max-res-version
        ignores versioned resource directories above the given value.
    --values
        when used with "dump resources" also includes resource values.
    --version-code
        inserts android:versionCode in to manifest.
    --version-name
        inserts android:versionName in to manifest.
    --replace-version
        If --version-code and/or --version-name are specified, these
        values will replace any value already in the manifest. By
        default, nothing is changed if the manifest already defines
        these attributes.
    --custom-package
        generates R.java into a different package.
    --extra-packages
        generate R.java for libraries. Separate libraries with ':'.
    --generate-dependencies
        generate dependency files in the same directories for R.java and resource package
    --auto-add-overlay
        Automatically add resources that are only in overlays.
    --preferred-density
        Specifies a preference for a particular density. Resources that do not
        match this density and have variants that are a closer match are removed.
    --split
        Builds a separate split APK for the configurations listed. This can
        be loaded alongside the base APK at runtime.
    --feature-of
        Builds a split APK that is a feature of the apk specified here. Resources
        in the base APK can be referenced from the the feature APK.
    --feature-after
        An app can have multiple Feature Split APKs which must be totally ordered.
        If --feature-of is specified, this flag specifies which Feature Split APK
        comes before this one. The first Feature Split APK should not define
        anything here.
    --rename-manifest-package
        Rewrite the manifest so that its package name is the package name
        given here.  Relative class names (for example .Foo) will be
        changed to absolute names with the old package so that the code
        does not need to change.
    --rename-instrumentation-target-package
        Rewrite the manifest so that all of its instrumentation
        components target the given package.  Useful when used in
        conjunction with --rename-manifest-package to fix tests against
        a package that has been renamed.
    --product
        Specifies which variant to choose for strings that have
        product variants
    --utf16
        changes default encoding for resources to UTF-16.  Only useful when API
        level is set to 7 or higher where the default encoding is UTF-8.
    --non-constant-id
        Make the resources ID non constant. This is required to make an R java class
        that does not contain the final value but is used to make reusable compiled
        libraries that need to access resources.
    --shared-lib
        Make a shared library resource package that can be loaded by an application
        at runtime to access the libraries resources. Implies --non-constant-id.
    --error-on-failed-insert
        Forces aapt to return an error if it fails to insert values into the manifest
        with --debug-mode, --min-sdk-version, --target-sdk-version --version-code
        and --version-name.
        Insertion typically fails if the manifest already defines the attribute.
    --error-on-missing-config-entry
        Forces aapt to return an error if it fails to find an entry for a configuration.
    --output-text-symbols
        Generates a text file containing the resource symbols of the R class in the
        specified folder.
    --ignore-assets
        Assets to be ignored. Default pattern is:
        !.svn:!.git:!.ds_store:!*.scc:.*:<dir>_*:!CVS:!thumbs.db:!picasa.ini:!*~
