Only use `install` when you explicitly need your built artifacts to be installed into your local Maven repository for use in other local builds. All other times, use `verify` instead, which should do everything `install` does, but without polluting your local maven repository with local builds (which can cause unexpected problems in some cases, and that can be confusing to novice Maven users).

Re: Need Help with Maven Build
I saw this problem a few times (usually when I build from IntelliJ console, after I changed to a different git branch). My solution is usually: git clean -xdf git reset --hard mvn clean after these steps usually "mvn clean install -DskipTests" works just fine On Wed, May 20, 2020 at 1:27 PM Jun Wang wrote: > I am using latest maven, build failed with zookeeper source code checked > out from github. but build is fine with downloaded source code > apache-zookeeper-3.6.1.tar.gz > > $ mvn --version > Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f) > Maven home: /home/jun/programs/apache-maven-3.6.3 > Java version: 1.8.0_251, vendor: Oracle Corporation, runtime: > /home/jun/programs/jdk1.8.0_251/jre > Default locale: en_US, platform encoding: UTF-8 > OS name: "linux", version: "4.10.0-38-generic", arch: "amd64", family: > "unix" > > > > From: Michael Han > Sent: Wednesday, May 20, 2020 1:08 AM > To: user > Cc: d...@zookeeper.apache.org > Subject: Re: Need Help with Maven Build > > hi jun - which maven version you are using? > > If it's 3.5.x, try upgrade to 3.6.x.

Re: Need Help with Maven Build
hi jun - which maven version you are using? If it's 3.5.x, try upgrade to 3.6.x. I had the exact same issue a while back and upgrade maven fixed this, so I didn't bother to debug. That said, it's interesting to understand why we failed under specific version of maven / env, so cc dev list where we have a few maven experts who might be able to help debug.

Need Help with Maven Build
Hi I got following build error with latest code from github. But build is fine with downloaded source code. Any suggestion is appreciated. [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile) on project zookeeper: Fatal error compiling: java.lang.NullPointerException -> [Help 1] https://gist.githubusercontent.com/wj1918/b1bcea0473b9ff2096ffa22e3c387e8f/raw/8c2ccfb7919470e0e874abdec5633976720e3dca/zookeeper.build.error.txt Thanks Jun
