Answer 1

I had have the same issue. As the first you can see that a new dexer called D8 is running. It seems to be still experimental so you can switch it off temporally in gradle.properties file by:

android.enableD8=false

See more details about D8 in a blog announcement

Then you can see more detailed error message which led me to following solution:

implementation("org.apache.oltu.oauth2:org.apache.oltu.oauth2.client:1.0.1") {
    exclude group: 'org.apache.oltu.oauth2', module: org.apache.oltu.oauth2.common'
}
