Docker Maven JAVA_HOME

[vaughnmb]

Using the latest version of the maven Docker image, I now get this error: The JAVA_HOME environment variable is not defined correctly.

I never encountered this issue with previous versions of the Maven Docker image. Is this by design and something I need to handle on my end?

May be related to #281 ? (Just based on timing, I did not look into it)

what image tag, what command,... are you trying to use

[mpaktheone]

Have same issue when use maven:latest when build docker container (command mvn build clean). When i am change it to maven:3.8.4 all build successful.
Problem start at may 30, because at may 27 everything was good.

[vaughnmb]

I am trying to use the maven:latest. The command was "mvn clean package"

[carlossg]

without more details I cannot help.

This works in this repo

docker run -it --rm -v "$(pwd)"/tests:/usr/src/mymaven -w /usr/src/mymaven maven:latest mvn clean package

what details do you need?
I have Dockerfile with content:
FROM maven:latest as build
WORKDIR /app
COPY mvnw .
COPY .mvn .mvn
COPY pom.xml .
RUN mvn build clean
....

and when im do:
docker build --rm --build-arg VERSION=test --tag test:test .

i get this error:
Step 6/57 : RUN mvn build clean
---> Running in 5587a9575359
The JAVA_HOME environment variable is not defined correctly,
this environment variable is needed to run this program.

if i change Dockerfile to
FROM maven:3.8.4 as build
WORKDIR /app
COPY mvnw .
COPY .mvn .mvn
COPY pom.xml .
RUN mvn build clean
....

all build successful
Problem start at may 30, because at may 27 everything was good.
