I have a system property configured in the maven jetty plugin, as follows:

<plugin>
<groupId>org.mortbay.jetty</groupId>
<artifactId>maven-jetty-plugin</artifactId>
<version>6.1.10</version>
<configuration>
<systemProperties>
<systemProperty>
<name>project.home</name>
<value>D:</value>
</systemProperty>
</systemProperties>
....
</configuration>
</plugin>

If I use this system property in logback –

<property file="${project.home}/foo/bar/baz/app.properties"/>

This system property is UNDEFINED when I run the webapp via mvn jetty:run.

The rest of the system (spring configuration files, etc) can happily use the project.home system property
except for logback.

The only way to run jetty now, with the correct substitution is through:

mvn jetty:run "-Dproject.home=D:"
