Hello Kuldeep,
did you download the source from the ZooKeeper webpage, or checked out from
git?
Anyway, the following commands should work:
wget
https://downloads.apache.org/zookeeper/zookeeper-3.5.7/apache-zookeeper-3.5.7.tar.gz
tar xzvf ./apache-zookeeper-3.5.7.tar.gz
cd apache-zookeeper-3.5.7
mvn clean install -DskipTests
I tested it with OpenJDK 8u424 and maven 3.6.0.
Kind regards,
Mate
