Matthias Pohl created FLINK-33291:
-------------------------------------
Summary: The release profile of Flink does include enforcing the
Java version only in a "soft" way
Key: FLINK-33291
URL: https://issues.apache.org/jira/browse/FLINK-33291
Project: Flink
Issue Type: Bug
Components: Build System
Affects Versions: 1.17.1, 1.16.2, 1.18.0, 1.19.0
Reporter: Matthias Pohl
The vote on 1.18.0-rc2
[revealed|https://lists.apache.org/thread/fbdl2w6wjmwk55y94ml91bpnhmh4rnm0]
that we don't do proper JDK version enforcement in {{release}} profile of the
Maven build.
This is added to ensure that Java 8 is used when releasing the artifacts. The
current configuration sets the version as a "soft" requirement (see
[documentation on
version|https://cwiki.apache.org/confluence/display/MAVENOLD/Dependency+Mediation+and+Conflict+Resolution#DependencyMediationandConflictResolution-DependencyVersionRanges]
which is referenced in the [Maven Enforcer Plugin
website|https://maven.apache.org/enforcer/maven-enforcer-plugin/]).
We should use square brackets to enforce the JDK version. The same can be
applied to the Maven version.
