Failed to exec spawn helper

When running docker-compose up I get:

------
executor failed running [/bin/sh -c gradle shadowJar]: exit code: 1
ERROR: Service 'slack_bot' failed to build : Build failed

Then I tried running Gradle with --info and it mentions an exception in Gradle:

#11 4.123 An attempt to start the daemon took 0.107 secs.
#11 4.144 
#11 4.144 FAILURE: Build failed with an exception.
#11 4.145 
#11 4.145 * What went wrong:
#11 4.146 A problem occurred starting process 'Gradle build daemon'

Then I run it with --stacktrace to get the exception details:

#11 4.163 Starting a Gradle Daemon (subsequent builds will be faster)

I don't know what else to try and the error details are not clear. Am I using the correct images?

Dockerfile:

WORKDIR /usr/src/app
COPY . .
RUN gradle shadowJar

FROM adoptopenjdk:latest

In my case, killing the existing gradle daemon fixed this. (A new one is automatically started with the next build op).

./gradlew --stop

What caused the issue in the first place was an upgrade of the IDE (Android Studio), which (I guess) wasn't able to reuse the daemon which the previous (old) instance started.

The JAVA_HOME system variable on the server running the IDE backend needs to be of version jdk11+, or as @Sai Srikar Mutya mentioned, add "-Djdk.lang.Process.launchMechanism=vfork" after "build process VM options" (I tried adding this parameter and it would compile the project particularly slowly).

The error is resolved by adding the below flag to File | Settings | Build, Execution, Deployment | Compiler | * build process VM options text field in Intellij

-Djdk.lang.Process.launchMechanism=vfork

Gradle 7.4.2 is broken. You should downgrade to 7.4.1

It doesn't fail to build - it already fails the start the Gradle daemon ...
This is the jspawnhelper at fault; it possibly might lack x permission:

RUN chmod +x $JAVA_HOME/lib/jspawnhelper
RUN gradle :shadowJar

Or disable the Gradle daemon altogether; with one-shot builds it doesn't make a difference.
Or try -Djdk.lang.Process.launchMechanism=vfork?
