Chesnay Schepler created FLINK-9582:
---------------------------------------
Summary: dist assemblies access files outside of flink-dist
Key: FLINK-9582
URL: https://issues.apache.org/jira/browse/FLINK-9582
Project: Flink
Issue Type: Bug
Components: Build System
Affects Versions: 1.5.0, 1.6.0
Reporter: Chesnay Schepler
Assignee: Chesnay Schepler
Fix For: 1.6.0
The flink-dist assemblies access compiled jars outside of flink-dist, for
example like this:
{code:java}
<source>../flink-libraries/flink-cep/target/flink-cep_${scala.binary.version}-${project.version}.jar</source>{code}
As usual, accessing files outside of the module that you're building is a
terrible idea.
It's brittle as it relies on paths that aren't guaranteed to be stable, and
requires these modules to be built beforehand. There's also an inherent
potential for dependency conflicts when building flink-dist on it's own, as
maven may download certain snapshot artifacts, but the assemblies ignore these
and bundle jars present in Flink.
We can use the maven-dependency plugin to copy required dependencies into the
{{target}} directory of flink-dist, and point the assemblies to these jars.
