[jetty-dev] [jira] (JETTY-1507) System properties are not getting cleared out between runs within an aggregator

Greg,

This is an issue with the Jetty plugin, not with the properties defined in the pom. It's not a Maven problem per se. It's a problem with the plugin's handling of system properties.
I removed all the systemProperties defined in the Jetty plugin. I then knocked up a simple Maven plugin, which sets system properties. With my plugin, the system properties are cleared between runs of the Jetty plugin in a multi-module aggregator which has more that one module running Jetty tests. (You can find my plugin here: https://github.com/carlspring/system-properties-maven-plugin ).

Also, the plugin doesn't set system properties which have already been set. This is kind of a limitation.
I worked around this problem by not using the <systemProperties> setting in the Jetty plugin and defining these properties in my plugin, but that should not be the way things work. In my opinion, the Jetty plugin should be able to override system properties and to make sure <systemProperties> are only defined for the scope of the execution.

> If you have an aggregator with several modules each of which launches Jetty before the tests and if you've defined <systemProperties><systemProperty...></systemProperties, the next module to start up Jetty will end up using the values from defined for the first module, even if you've defined different values for this module.
