Steps to Reproduce
Robolectric & Android Version
compileSdkVersion 25
buildToolsVersion "25.0.2"
minSdkVersion 15
targetSdkVersion 25
testCompile 'org.robolectric:robolectric:3.2.2'

Answer 1

I faced this same issue due to previously failed repository download.
As I was targeting sdk 23, I deleted 6.0.1_r3-robolectric-r1 directory which triggered re-download & fixed this issue.
rm -rf /home/user/.m2/repository/org/robolectric/android-all/6.0.1_r3-robolectric-r1

Answer 2

I've had this in a kotlin test and fixed it by opening up my test-class:
#RunWith(RobolectricTestRunner::class)
#Config(sdk = [23], constants = BuildConfig::class)
open class MyExampleTest {
Applied to java this means your test class shouldn't be final
.

Answer 3

A previously failed repository download could result in this issue.
• Delete the existing roboelectric version
in /home/user/.m2/repository/org/robolectric/android-all.
• Re-run your tests (robolectric will be re-downloaded in the process).
