I am a newbie of Livy and I build Livy as the official said. The command is as follows:

git clone https://github.com/apache/incubator-livy.git

cd incubator-livy

mvn package

Then I get error as follows：

[ERROR] Plugin org.apache.maven.plugins:maven-enforcer-plugin:1.4.1 or one of its dependencies could not be resolved: Failure to find org.apache.maven.plugins:maven-enforcer-plugin:jar:1.4.1 in http://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced ->`

I clean the ~/.m2/ and I use mvn -U clean package, it failed too. Could anyone help me? Thank you

    What happens if you point your browser to https://repo.maven.apache.org/maven2/org/apache/maven/plugins/maven-enforcer-plugin/1.4.1/maven-enforcer-plugin-1.4.1.jar , do you get an error or do you see an JAR file? – Ferrybig Sep 04 '17 at 06:53
  • Its there http://repo.maven.apache.org/maven2/org/apache/maven/plugins/maven-enforcer-plugin/ – Naman Sep 04 '17 at 06:54
  • @Ferrybig I use my browser to visit the url and download `maven-enforcer-plugin-1.4.1.jar` – GOGO Sep 04 '17 at 07:00
  • @nullpointer I can not understand what you say. Could you explain it for me? – GOGO Sep 04 '17 at 07:02
  • I use `curl -O https://repo.maven.apache.org/maven2/org/apache/maven/plugins/maven-enforcer-plugin/1.4.1/maven-enforcer-plugin-1.4.1.jar` and also download the jar to my machine. – GOGO Sep 04 '17 at 07:12

Install python package as follows:

It will work
