[JBoss JIRA] Created: (JBRULES-2676) When rebuilding from source with -Declipse option on OSX / Linux systems, the Eclipse tar.gz file is unnecessarily reloaded

When rebuilding from source with -Declipse option on OSX / Linux systems, the Eclipse tar.gz file is unnecessarily reloaded ---------------------------------------------------------------------------------------------------------------------------- Key: JBRULES-2676 URL: https://jira.jboss.org/browse/JBRULES-2676 Project: Drools Issue Type: Bug Security Level: Public (Everyone can see) Components: drools-eclipse Affects Versions: FUTURE Environment: Occurs on family 'mac' and 'unix' systems where the eclipse file download extension is 'tar.gz' format, instead of 'zip' as on Windows Reporter: Lawrence Terrill Assignee: Mark Proctor Priority: Minor When building the eclipse component from source, the eclipse tar.gz file is repeatedly downloaded despite a check for the file's existance. In the file drools-eclipse/drools-eclipse-build/setupEclipse.xml, target 'checkEclipseJar', the existance of the file is checked. But this check is hardcoded with the file extension '.zip'. It likely should have used the symbolic '${download.extension}' used in the 'getEclipseJar' target in the same file. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
