Bug 59428

I'm trying to create .xlsx documents with the Apache POI 3.14 library.

This is my Gradle config:

(...)    
defaultConfig {
            applicationId "com.example.app"
            minSdkVersion 14
            targetSdkVersion 19

            multiDexEnabled true

        }

        buildTypes {
            release {
                minifyEnabled true
                proguardFiles getDefaultProguardFile('proguard-android.txt')
                proguardFile 'Path/app/proguard-rules.pro'
            }
        }
    }

    dependencies {
        compile 'com.android.support:appcompat-v7:22.2.0'
        compile 'com.android.support:multidex:1.0.1'
        //compile files('libs/android-support-v13.jar')
        compile files('libs/commons-io-2.4.jar')
        compile files('libs/commons-net-3.3.jar')
        compile files('libs/poi-3.14-20160307.jar')
        compile files('libs/poi-ooxml-3.14-20160307.jar')
        compile files('libs/poi-ooxml-schemas-3.14-20160307.jar')
        compile files('libs/xmlbeans-2.6.0.jar')
        compile files('libs/curvesapi-1.03.jar')
        compile files('libs/commons-codec-1.10.jar')
        compile files('libs/commons-logging-1.2.jar')
        compile files('libs/junit-4.12.jar')
        compile files('libs/log4j-1.2.17.jar')
        compile 'com.roomorama:caldroid:2.3.1'

    }
With the original xmlbeans library xmlbeans-2.6.0.jar I get this exception when I try to run APP

Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'.
> com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: org/apache/xmlbeans/xml/stream/Location.class
I've tried to remove the duplicated class with this method

-Unzip the jar file. (Simply change .jar extension to .zip
-This will remove the duplicate files.
-Recreate the jar using jar cf xmlbeans.jar -C (path to unzipped folder) . (Mind it, there is a dot in the end of command)
-Use this regenerated jar
When I try to run the app with this recompiled .jar I get this warnings but even so it is launched to the device

    Error:warning: Ignoring InnerClasses attribute for an anonymous inner class
    Error:(org.apache.xmlbeans.impl.inst2xsd.RussianDollStrategy$1) that doesn't come with an
    Error:associated EnclosingMethod attribute. This class was probably produced by a
    Error:compiler that did not target the modern .class file format. The recommended
    Error:solution is to recompile the class from source, using an up-to-date compiler
    Error:and without specifying any "-target" type options. The consequence of ignoring
    Error:this warning is that reflective operations on this class will incorrectly
    Error:indicate that it is *not* an inner class.
(...)
Then when in my code try to do :

XSSFWorkbook wb = new XSSFWorkbook();
I get this exception and closes the app

What would be wrong?
