There is a ClassCastException

org.gradle.api.internal.tasks.DefaultTaskInputs$TaskInputUnionFileCollection cannot be cast to org.gradle.api.internal.file.collections.DefaultConfigurableFileCollection

There is another post that discusses this but that was for an older version.

I have:
ignisvulpis@namenlos:~/development/Android-IMSI-Catcher-Detector$ gradle -v

Gradle 3.2.1

  • What went wrong:
    A problem occurred configuring project ‘:AIMSICD’.

// Sorry for the stupid title. The forum forced me.

Did you try out the Android plugin version as suggested in the other post?

No. I downgraded to gradle-2.1.4 and the build works.

ignisvulpis@namenlos:~$ gradle -v

Gradle 2.14.1

Build time: 2016-07-18 06:38:37 UTC
Revision: d9e2113d9fb05a5caabba61798bdb8dfdca83719

Groovy: 2.4.4
Ant: Apache Ant™ version 1.9.6 compiled on June 29 2015
JVM: 1.8.0_111 (Oracle Corporation 25.111-b14)

I still think that something is wrong with the new release.

s/2.1.4/2.14.1/
wrong version

You shouldn’t have to downgrade to an older version of Gradle. It’s actually better to move forward as you reap the benefits of other improvements in Gradle (most importantly performance). I believe to be able to use the Android plugin with the latest version of Gradle you’ll have to upgrade to the suggested Android plugin version.

Thanks. Still gradle 3.2.1 should should not crash anyway, right?!

The Android plugin likely uses internal APIs which simply became incompatible with API of Gradle 3.2.1. Therefore, the Android plugin released a new version to fix the issue. Is there any good reason not to upgrade to the latest Android plugin version?

dependencies {
classpath ‘com.android.tools.build:gradle:2.2.0’

works. Thank you.
Can’t gradle detect that 2.1.3 is not compatible with it?

That works with a from-source complied version of gradle too while the old Android plugin did not like the version number 3.4-20161214100956+0000

Gradle itself doesn’t know about external plugins. It’s up to the plugin to make the determination if it is compatible. I believe the Android plugin have a check built-in at some point of time. They might have taken it out. You might want to ask on the mailing list/user forum.
