[jira] Created: (MCOMPILER-82) is compiler correct ? is jdk path
correct? how to verify ?
is compiler correct ? is jdk path correct? how to verify ?
------------------------------------------------------------
Key: MCOMPILER-82
URL: http://jira.codehaus.org/browse/MCOMPILER-82
Project: Maven 2.x Compiler Plugin
Issue Type: Improvement
Affects Versions: 2.0.2
Environment: unix
Reporter: Michael Meng
Priority: Critical
We have the $JAVA_HOME set to /usr/jdk1.5.0_11, which is the jdk1.5.0_11 location.
In the maven-compiler-plugin, it says -- The default compiler is javac and is used to compile Java sources
1. which javac it points to ? is it the javac under JAVA_HOME/bin ?
2. If yes, since we use the jdk1.5 already, why we still need to define the
<source>1.5</source>
<target>1.5</target>
?
3. Please confim that the compiler does not use the JDK that run Maven with.
Thanks
Michael

Assignee: Benjamin Bentmann
Resolution: Not A Bug
Please don't misuse the issue tracker for questions but rather post to the [user mailing list|http://maven.apache.org/mail-lists.html].
bq. 1. which javac it points to ? is it the javac under JAVA_HOME/bin ?
Unless you configured the plugin to use a specific JDK as described in the example [Compiling Sources Using A Different JDK|http://maven.apache.org/plugins/maven-compiler-plugin/examples/compile-using-different-jdk.html], the plugin uses the javac from the JDK used to run Maven.
To verify the command line Maven uses to invoke javac, you just need to enable Maven's debug logging by passing the {{-X}} on the command line.

2. If yes, since we use the jdk1.5 already, why we still need to define the
<source>1.5</source>
<target>1.5</target>
{quote}
Because the Maven Compiler Plugin has built-in default values for these settings, c.f the first paragraph of the [plugin index page|http://maven.apache.org/plugins/maven-compiler-plugin/].
