[jira] Moved: (MCOMPILER-144) Using compiler API instead of
tools.jar
[ http://jira.codehaus.org/browse/MCOMPILER-144?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Brett Porter moved MNG-4981 to MCOMPILER-144:
---------------------------------------------
Complexity: (was: Intermediate)
Component/s: (was: Bootstrap & Build)
Affects Version/s: (was: 3.1)
Key: MCOMPILER-144 (was: MNG-4981)
Project: Maven 2.x Compiler Plugin (was: Maven 2 & 3)
> Using compiler API instead of tools.jar
> ---------------------------------------
>
> Key: MCOMPILER-144
> URL: http://jira.codehaus.org/browse/MCOMPILER-144
> Project: Maven 2.x Compiler Plugin
> Issue Type: New Feature
> Reporter: Markus KARG
> Priority: Minor
>
> Currently (MVN 3.0) java compilation needs tools.jar provided by the Sun JDK:
> [ERROR] Unable to locate the Javac Compiler in:
> [ERROR] C:\Program Files\Java\jre6\..\lib\tools.jar
> [ERROR] Please ensure you are using JDK 1.4 or above and
> [ERROR] not a JRE (the com.sun.tools.javac.Main class is required).
> [ERROR] In most cases you can change the location of your Java
> [ERROR] installation by setting the JAVA_HOME environment variable.
> In fact, this is bad because (a) it assumes that a full JDK is installed just for this sole tool where a JRE would be sufficient, (b) tools.jar is not contained in any standards documents and such possibly is not existing on future or non-sun JDK.
> Since JRE 6 (i. e. for many years) the JRE (not JDK!) comes with a standardized (!) API for compilation: The Java Compiler API. It would make sense to use that standardized API instead of forcing the user to have Sun JDK installed.
