Bitrise Build Issue Report template

Description of the issue

We have written our unit tests using the Mockk Framework:
testImplementation "io.mockk:mockk:1.9.1"

This is the testImplementation section of our gradle file as it stands today:
testImplementation “androidx.test.espresso:espresso-core:3.3.0”
testImplementation “androidx.test.ext:junit:1.1.2”
testImplementation ‘androidx.test:core-ktx:1.3.0’
testImplementation ‘androidx.test.espresso:espresso-core:3.3.0’
testImplementation ‘androidx.test.ext:junit:1.1.2’
testImplementation ‘androidx.test:runner:1.3.0’
testImplementation(“com.jakewharton.retrofit:retrofit2-kotlinx-serialization-converter:0.8.0”)
testImplementation “com.squareup.okhttp3:mockwebserver:4.2.1”
testImplementation “com.willowtreeapps.assertk:assertk-jvm:0.20”
testImplementation “io.kotlintest:kotlintest-runner-junit5:3.4.2”
testImplementation “io.mockk:mockk:1.9.1”
testImplementation “org.assertj:assertj-core:3.13.2”
testImplementation “org.hamcrest:hamcrest-library:2.2”
testImplementation group: ‘org.jetbrains.kotlinx’, name: ‘kotlinx-serialization-runtime-common’, version: ‘0.4.1’
testImplementation(“org.jetbrains.kotlinx:kotlinx-serialization-json:1.1.0”)
testImplementation(“org.jetbrains.kotlin:kotlin-reflect:$coroutines_version”)
testImplementation “org.mockito:mockito-core:3.1.0”
testImplementation “org.robolectric:robolectric:4.4”
testImplementation “org.slf4j:slf4j-simple:1.7.28”

For the sake of troubleshooting on Bitrise, I have removed all except for a single unit test. The unit test is failing on Bitrise. The symptoms are similar to this thread. I followed the suggestions provided in that thread to no prevail.

This is the error that I received:
* What went wrong:

    Execution failed for task ':tradesy:testDevDebugUnitTest'.
    > Received a completed event for test with unknown id '7.4'. Registered test ids: '[7.2, 7.1, :tradesy:testDevDebugUnitTest]'

If you have access, a link to the most recent log is located here.

Environment:

Where did the issue happen?

If on Bitrise.io: which stack? If not on Bitrise.io: on what operating system? (Plus any other information you can share)
The failure occurred on Bitrise, Android + Docker on Ubuntu 16.04

Which build Step causes the issue and which version of the step?
android-unit-test

Reproducibility

• Does a “Rebuild” help? (You can trigger a rebuild from the Build’s page, by clicking the “Rebuild” button in the top right corner of a finished build) : NO
• Does a rebuild without caches help? (You can remove the Cache:Pull and Cache:Push steps temporarily to not to use the cache, or you can delete all the caches on the Settings tab of the app. : NO
• Does the issue happen sporadically, or every time? : Every time
• Does upgrading the build Step to the latest version help? : NO
• When did the issue start? : I created this app today, and pointed to a particular branch, which contains the latest source code changes exclusively for Bitrise.

Local reproduction

Can it be reproduced on your own Mac/PC by following our local debug guide? Please follow at least the first section (“Testing with a full clean git clone”) to make sure to test the state of the code what bitrise.io will get when it does a git clone in the clean environment! If possible please note which sections you tried.

Local reproduction: Linux / Android (docker based) stack builds

Can it be reproduced by running the build locally, after doing a new git clone of the repository into the /tmp directory and running the build from there with the Bitrise CLI ( Bitrise CLI )? If no, can it be reproduced with Docker (using the same docker images / environment we use on bitrise.io)? Related guide: Redirecting… .

I see that the JVM on Bitrise differs from that on my local machine:
+ /bitrise/src/gradlew tasks --v
------------------------------------------------------------
Gradle 7.0

Build time: 2021-04-09 22:27:31 UTC
Revision: d5661e3f0e07a8caff705f1badf79fb5df8022c4
Kotlin: 1.4.31
Groovy: 3.0.7
Ant: Apache Ant™ version 1.10.9 compiled on September 27 2020
JVM: 1.8.0_282 (Private Build 25.282-b08)
OS: Linux 4.4.0-57-generic amd64

Is it possible to change the JVM on Bitrise?

Hello there,

In case someone else has the same issue, our experts advise switching to JDK 11 in place of JDK 14, as this is known to be working on our stacks and this usually resolves the usual Java problems for customers.
