[jira] Commented: (MNGECLIPSE-89) Compile goal fails with exception

["Charlie Dobbie (JIRA)" <ji...@codehaus.org>]

    [ http://jira.codehaus.org/browse/MNGECLIPSE-89?page=comments#action_65670 ] 

Charlie Dobbie commented on MNGECLIPSE-89:
------------------------------------------

Just had the same problem - also fixed by changing Eclipse to use a JDK rather than a JRE, many thanks!  For anyone who has this problem, the workaround is as follows:

In Eclipse select Window > Preferences > Java > Installed JREs.
Click Add.
Browse to the root of the JDK directory (e.g. C:\Program Files\Java\jdk1.5.0_05)
Give the "JRE" a name (e.g. JDK 1.5.0_05)
OK the dialog.
Check the JDK, uncheck the JRE.
OK the dialog.

Your project should automatically switch to using this new JDK.  If it does not:

Right click the project directory, select Properties > Java Build Path > Libraries.
Select the JRE System Library, click Edit.
Select Alternate JRE, select the JDK, OK all dialogs.
