[jboss-jira] [JBoss JIRA] Commented: (JBRULES-1733) Set execution environment in project's build path.

[Faron Dutton (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBRULES-1733?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12434289#action_12434289 ] 

Faron Dutton commented on JBRULES-1733:
---------------------------------------

Every system is different, which is the point of this issue. Setting the execution environment in Eclipse just states that the project requires a version of the JDK at or above the specified value. For example, specifying J2SE-1.5 informs Eclipse that the compiler must be set to produce either 1.5 or 1.6 (currently) bytecode and that the requisite libraries must be available. It does not say where these libraries must reside and it does not fail if the user chooses something different from the project's developers. By not specifying the execution environment, you are saying that any will do. This causes the project to fail is the user's default JRE is older that the one needed, which is what happened to me. I usually keep my default set to J2SE-1.4 so that the code I write is backward compatible and explicitly set the execution environment on every project. I have a copy of each targeted J2SE environment for this purpose and for testing.

> Currently, each Drools project relies on the default Eclipse JRE container, which varies from one developer to another. Configuring the execution environment in a project's classpath will remove the need for a developer to alter the classpath on checkout.
