             Summary: need <skip> option for evaluate goal
                 Key: MPH-192
                 URL: https://issues.apache.org/jira/browse/MPH-192
             Project: Maven Help Plugin
          Issue Type: New Feature
          Components: evaluate
    Affects Versions: 3.3.0
            Reporter: Garret Wilson


It is typical and even expected for Maven plugins to have a {{<skip>}} option, 
so that we can provide (via properties, profiles, etc.) a way to skip the 
plugin execution. See for example the [Antrun Plugin {{<skip>}} 
option|https://maven.apache.org/plugins/maven-antrun-plugin/run-mojo.html#skip] 
and the [Maven Assembly Plugin {{<skipAssembly>}} 
option|https://maven.apache.org/plugins/maven-assembly-plugin/single-mojo.html#skipAssembly].
 (I could provide a long list of similar plugins.)

Please provide a Maven configuration option to skip execution for the 
{{evaluate}} goal.

This is particularly important because the Maven Help Plugin provides the only 
means to generate output to a file which is recognized across many development 
environments. (For example, Antrun {{<echo>}} can generate a file, but it is 
not supported by Eclipse.)

It is important to be able to able to configure in the POM to evaluate an 
expression and output to a file _only_ under certain conditions. Currently the 
lack of this functionality is blocking my use of the Maven Help Plugin 
{{evaluate}} goal and I am forced to look for other options, or limp along with 
Antrun not working in Eclipse.

Thank you.
