Android - Proguard zurückgegeben, die mit error code 1

Wollte ich meine app progaurd geschützt. Für diese ging ich durch einige tutorials, Beiträge und endlich aus diese post kam ich zu wissen, dass ich, sollte dies nur tun:

If you're using ADT 17 or newer, the documentation is slightly inaccurate. The generated file is proguard-project.txt and will be in the root directory of your project.

To enable Proguard, you will need to ignore the "do not modify" warning in project.properties and uncomment the following line:

proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt

Nach uncommeting der oben vorgeschlagenen Linie habe ich versucht zu exportieren, die nicht signierte Anwendung. Bekam aber ein export-Fehler sagen progaurd returned error with code 1 . Wenn ich klickte die Schaltfläche details auf der Fehler-dialog, bekam ich die Fehler melden, die unten gezeigt:

Proguard returned with error code 1. See console
