| Choosing a JRE for a launch configuration |
| </h1> |
| <p> |
| Instead of using the default JRE for running and debugging all <strong>Java Application</strong> launch configurations, you can specifically assign a JRE for launching an individual |
| configuration. </p> |
| <ol> |
| <li> |
| With a Java Application configuration selected in the |
| <a class="command-link" href='javascript:executeCommand("org.eclipse.debug.ui.commands.OpenRunConfigurations")'> |
| <img src="PLUGINS_ROOT/org.eclipse.help/command_link.svg" alt="Opens the Launch Configuration dialog"> |
| <strong>Launch Configuration Dialog</strong></a>, select the JRE tab. |
| </li> |
| <li> |
| In the list of available JREs, select the JRE you want to use to launch this configuration and click <strong>Apply</strong>, then <strong>Run</strong> or <strong>Debug</strong>. </li> |
| </ol> |
| <p> |
| <strong>Note</strong>: Changing the JRE used for running does not affect the way Java source is compiled. You can adjust the build path to compile against custom |
| libraries. |
