bootstrap class path not set in conjunction with -source 1.6

Question

I am upgrading my application from java 1.6 to 1.7. When I try to build using Maven 3.2.1, my build fails with below error msg:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.0.2:compile (default-compile) on project my-app5: Compilation failure: Compilation failure:
[ERROR] could not parse error message: warning: [options] bootstrap class path not set in conjunction with -source 1.6  

I am using java 1.7 hotspot and previously I was using 1.6 jrockit. My application is multi module and few modules compile and build as usual, this module failed.

I have set java home properly and mvn --version shows below output:

Apache Maven 3.2.1 (ea8b2b07643dbb1b84b6d16e1f08391b666bc1e9; 2014-02-14T23:07:52+05:30)
Maven home: C:\Users\me\Maven3\apache-maven-3.2.1-bin\apache-maven-3.2.1\bin\..
Java version: 1.7.0_51, vendor: Oracle Corporation
Java home: C:\Program Files\jdk17051\jre
Default locale: en_US, platform encoding: Cp1252
OS name: "windows 7", version: "6.1", arch: "amd64", family: "windows"  

Am I missing anything?

Answer 1

I solved it using below configuration in my compiler plugin:

<fork>true</fork>
<executable>${JAVA_HOME}/bin/javac</executable>
<compilerVersion>1.7</compilerVersion>
<source>1.7</source>
<target>1.7</target>  

This will use the JDK which you have defined in your JAVA_HOME environment property.
