Trouble with ${revision} in Docker builds

[miles-po]

pom.xml has <version>${revision}</version> with a corresponding <revision>0.0.9</revision> in the <properties> section. Running mvn clean package from terminal and from within IntelliJ work fine. However same code building from Docker fails.

When I replace ${revision} and ${changelist} with explicit versions instead of property references, it builds fine.

Relevant Dockerfile snippet leading up to RUN error.

FROM maven:3-eclipse-temurin-21-alpine AS build
WORKDIR /build
COPY . .
RUN mvn clean package --batch-mode -DskipTests

returns

Fixed by adding the following after COPYing the pom.xml file into the container image:

RUN sed -i "s/\${revision}/$(awk -F'[<>]' '/<revision>/{print $3}' pom.xml)/g" pom.xml

Reads the revision parameter and then replaces the ${revision} placeholder in the pom file. Uses sed and awk, so should be available in any Linux container.
