bootstrap class path not set in conjunction with -source 1.6
Quote from this post:
Java 5.0 and 6 used to have poor support for compiling classes to target older versions of Java. It always supported the previous version, but often no more. Even if you could compile for previous version, you had to be careful not to use functionality which did exist in the previous versions.
You should either include -Xbootclasspath
when using javac:
javac -Xbootclasspath:/path/to/jdk6/rt.jar -target 1.6 -source 1.6 Main.java
or compile using -target 1.7
(or higher of course):
javac -target 1.7 -source 1.7 Main.java
or use javac
of jdk 6:
/path/to/jdk6/bin/javac Main.java
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.
