John Fang created FLINK-8567:
--------------------------------
Summary: Maven-shade-plugin can't relocate Scala classes.
Key: FLINK-8567
URL: https://issues.apache.org/jira/browse/FLINK-8567
Project: Flink
Issue Type: Bug
Components: Table API & SQL
Affects Versions: 2.0.0, 1.5.0
Reporter: John Fang
Fix For: 2.0.0
Attachments: exclude_guava.patch
Maven-shade-plugin only relocate java classes, but not Scala classes. I try to
decompile flink-table Jar, and find those guava path not beed relocated on
those Scala classes. But flink job run normally for all time. Because
flink-dist_${scala.binary.version}.jar contains the google guava and flink
shaded guava at the same time. Why is the google guava still contained int the
flink?
Because we build flink by Maven-assembly-plugin at flink-disk module. The
Assembly Plugin aggregate its all dependencies, includes those dependencies
which are shaded now. If we use the following patch which exclude the Guava,
then the flink-dist_${scala.binary.version}.jar only contains the
flink-shaded-guava, not the google guava.
