By default, the Maven Javadoc Plugin tries to auto-detect the Javadoc Tool executable from the Java property java.home or from the environment variable JAVA_HOME .
You could also specify the executable of the Javadoc Tool to use. For example:
<project> ... <reporting> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-javadoc-plugin</artifactId> <configuration> <javadocExecutable>C:\jdk1.6.0\bin\javadoc.exe</javadocExecutable> ... </configuration> </plugin> ... </plugins> </reporting> ... </project>
In the same way, the Maven Javadoc Plugin tries to auto-detect the Javadoc Tool version by calling javadoc -J-fullversion .
You could also specify the version of the Javadoc Tool executable. For example:
<project> ... <reporting> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-javadoc-plugin</artifactId> <configuration> <javadocVersion>1.5</javadocVersion> ... </configuration> </plugin> ... </plugins> </reporting> ... </project>
Note : You could have a warning if the javadocVersion specified is not the same that the Javadoc Tool executable.
