Robert Scholte closed MEXEC-78.
-------------------------------
Resolution: Won't Fix
Assignee: Robert Scholte
With MEXEC-82 it's possible to skip the execution. Combining this with profiles
( http://maven.apache.org/guides/introduction/introduction-to-profiles.html )
you should be able to get the same result. Preconditions shouldn't be resolved
in the plugin itself.
> Added a precondition to skip execution by existence or absence of a file

> Project: Maven 2.x Exec Plugin
> Issue Type: Improvement
> Components: exec
> Affects Versions: 1.1.1
> Environment: exec-maven-plugin version 1.1.1
> Reporter: Maik Richey

>
> In our scenario one execution of the exec plugin can be called multiple times
> for generating a specific file. As an enhancement to our build process I
> added a precondition to skip execution by existence or absence of that file
> (see configuration below). So if the file specified is missing and should
> exist _or_ is existing and should be missing execution will be skipped. Valid
> preconditions are missing and exists (similar to activation of profiles).
