My company recently moved our Artifactory instance from HTTP to HTTPS, so we need to provide Maven with a path to a trust store. I have set a global environment variable in Windows:

MAVEN_OPTS=-Djavax.net.ssl.trustStore=C:\path\to\store -Djavax.net.ssl.trustStorePassword=password

This is picked up fine by Maven when I build, either within Netbeans or in cmd/cygwin/etc.

However, since the move, I can no longer download sources for my dependencies (from the right-click menu, either directly on a particular artifact or download-all). There are no errors in the IDE log.

It seems to me that the Netbeans Maven plugin is ignoring, or overriding, the system MAVEN_OPTS.

When I try to index, I get the following related error:
