Well, that reference had a lot of helpful information, but it still
isn't working for me.
I have this in my settings.xml:
<settings>
<profiles>
<profile>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<properties>
<devenv71Path>C:\a\b\71</devenv71Path>
</properties>
</profile>
</profiles>
<pluginGroups>
<pluginGroup>no.fast.buildprocess</pluginGroup>
</pluginGroups>
</settings>
According to the intro to profiles page, I should be able to put this in
my pom.xml to configure my plugin using this value:
<build>
<plugins>
<plugin>
<groupId>no.fast.buildprocess</groupId>
<artifactId>vstudio</artifactId>
<executions>
<execution>
<goals>
<goal>buildsln</goal>
</goals>
<configuration>
<devenv71Path>${devenv71Path}</devenv71Path>
<solutionDir>src/main/cpp/myproject</solutionDir>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
(The fact that my property name matches the plugin configuration
property name is just a coincidence--I get the same result if the names
are different.)
When I execute the goal, however, all I get is a NullPointerException:

Should this work? Am I using the wrong syntax?
I'd really like to be able to make the plugin read the property from
settings.xml directly, and have the property be optional (so it uses a
default if the property isn't set). Is this possible?

Hi David,
Check out this url from the Maven documentation for setting the
configuration in the settings.xml file:
