Import Maven project “YCSB” into Eclipse

Question

Can someone tell me the right way to import a Maven Project (in my case YCSB) into Eclipse Luna? I am trying it via Import > Maven > Existing Maven Projects . Eclipse imports all the folders and files, but there is an error in every folders POM.xml.

Plugin execution not covered by lifecycle configuration:
org.apache.maven.plugins:maven-checkstyle-plugin:2.15:checkstyle (execution: validate, phase: validate)

Also I have no idea how to build and run the the project. I tried it by configuring a Maven Run Configuration with the goals clean package and compiled. The Build fails with following Console output.

Building the project with the commandline command mvn clean package builds the project without an error.

My system has Ubuntu 14.04 and Maven 3 installed.

Answer 1

First, This error

Plugin execution not covered by lifecycle configuration:
org.apache.maven.plugins:maven-checkstyle-plugin:2.15:checkstyle (execution: validate, phase: validate)

happend because you haven't the "Eclipse Checkstyle Plug-in" installed in eclipse. In eclipse menu:Help->install new software ,enter this site http://eclipse-cs.sourceforge.net/update search checkstyle and install this plugin,the error in your pol.xml will all disapear.

Second,this error

Plugin org.apache.maven.plugins:maven-surefire-plugin:2.12.4 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-surefire-plugin:jar:2.12.4: Could not transfer artifact org.apache.maven.plugins:maven-surefire-plugin:pom:2.12.4 from/to central (http://repo.maven.apache.org/maven2): repo.maven.apache.org: Der Name oder der Dienst ist nicht bekannt: Unknown host repo.maven.apache.org:
 Der Name oder der Dienst ist nicht bekannt-> [Help 1]

indicates that your internet connection is broken and maven can not download the dependent jar file for compiling. Check you internet connection or configure a proxy for maven. When the above is down, use mvn clean package to compile maven.You can also use mvn -pl com.yahoo.ycsb:mongodb-binding -am clean package to compile a certain database binding only.

Answer 2

yes it is right way to import maven project in eclipse but you got some errors. please check error on error window(window->show view ->General->error log) then you get actual error.
