Not able to do clean package

[beigithub]

Hi, I tried to run the following statement:======================== echo $JAVA_HOME /export/apps/jdk/JDK-1_8_0_40 cd mysql_perf_analyzer-master /apache-maven-3.0.5/bin/mvn clean package

When I run as non-root user, I get below error message:===================== Error: Could not find or load main class org.codehaus.plexus.classworlds.launcher.Launcher

When I run as root, I get further but still error:=========================== [WARNING] [WARNING] Some problems were encountered while building the effective model for com.yahoo.dba.perf:myperf:war:2.0.0-SNAPSHOT [WARNING] 'build.plugins.plugin.version' for org.apache.maven.plugins:maven-source-plugin is missing. @ line 131, column 12 [WARNING] [WARNING] Some problems were encountered while building the effective model for com.yahoo.dba.tools:myperfserver:jar:2.0.0-SNAPSHOT [WARNING] 'build.plugins.plugin.version' for org.apache.maven.plugins:maven-compiler-plugin is missing. @ line 92, column 12 [WARNING] 'build.plugins.plugin.version' for org.apache.maven.plugins:maven-source-plugin is missing. @ line 104, column 12 [WARNING] [WARNING] It is highly recommended to fix these problems because they threaten the stability of your build.

Please advice

What is your output of "javac -version" and "java -version"?

[xrao]

Just did a test. If you have multiple Java/JDK installed, make sure you have /export/apps/jdk/JDK-1_8_0_40/bin in your PATH env before other java path.

[beigithub]

I also have the 1.6 installed, however, JAVA_HOME is set to 1.8, and the $PATH had 1.8 also, [bxu@bxu-ld1 ~]$ javac -version javac 1.6.0_27 [bxu@bxu-ld1 ~]$ java -version java version "1.6.0_27" Java(TM) SE Runtime Environment (build 1.6.0_27-b07) Java HotSpot(TM) 64-Bit Server VM (build 20.2-b06, mixed mode)

I will put 1.8 in front of /usr/bin and try

[beigithub]

No luck, 1.6 is in /usr/bin, I change the $PATH to have 1.8 in front of the /usr/bin, still same error, please advice.

[xrao]

At the end of /home/bxu/Downloads/apache-maven-3.0.5/bin/mvn, you will see the actual java command and class path maven uses. You can modify the mvm script to print out two variables: $M2_HOME and $JAVACMD. mvn is expecting a jar file like $M2_HOME/boot/plexus-classworlds-*.jar.

Rao, thanks for pointing me to the right direction, the M2_HOME was set wrong, after I point it to the right path, it pass with flying colors, thanks!
