Hi, I was trying to build a game, but I got this weird error that prevents me from building the game. So, the error is:-

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

     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:!*~
    ]
    stdout[
   
    ]

I will be thankful for any help. Thanks in advance.

The AAPT is one tool in the Android toolchain that Unity calls to build the game.

Looking at the command line used by Unity, the --extra-packages is not followed by anything. The documentation that you attached mention this:

This means that this parameter should be followed by libraries or paths to libraries.
Digging up (using a .NET decompiler) to see where Unity invokes this command gets us this:

if (androidLibraries.Count > 0)
{
    text2 += string.Format (" --extra-packages {0}", string.Join (":", androidLibraries.GetPackageNames ()));
    string[] resourceDirectories = androidLibraries.GetResourceDirectories ();
    for (int i = 0; i < resourceDirectories.Length; i++)
    {
        string arg = resourceDirectories [i];
        text2 += string.Format (" -S \"{0}\"", arg);
    }
}

At this point, i’d be interested in how your project is setup and whether you’r using any android libraries ? What do you have under your Assets/Plugins/Android folder ?

Thank you for your response.
I am using a plugin called play game services. I got it from git hub. Do you think this plugin is causing this error?
