'Invalid or missing parameters' problem when running plugin

[aldana <al...@gmx.de>]

hi,

i am using mojo-executor extension (http://code.google.com/p/mojo-executor/)
which i use for my custom plugin to call up jetty-maven-plugin.

problem is that somehow properties are getting overridden, when the jetty
plugin is called up:
 org.mortbay.jetty:maven-jetty-plugin. Reason: Invalid or missing
parameters: [Mojo parameter [name: 'project'; alias: 'null']] for mojo:
org.mortbay.jetty:maven-jetty-plugin:6.1.16:run

could it be that mojo-executor isn't passing through the ${project} variable
to jetty-plugin correctly? the error message tells me that it cannot find
the ${project} parameter doesn't it?

Re: 'Invalid or missing parameters' problem when running plugin

I found the reason, I had a look at the maven jetty plugin source code and it
says:

    /**
     * The maven project.
     *
     * @parameter expression="${executedProject}"
     * @required
     * @readonly
     */
    protected MavenProject project;


Unfortunately the stack trace doesn't say something about missing param
'${executedProject}', but  the fieldname. Still it is unclear to me what is
setting the parameter ${executedProject} before running the jetty:run goal.

First I thought it would be triggered by package-type war, but this isn't
the case. 

How can I find out where certain property settings is coming from or what
plugin was setting it (could not see anything through 'mvn -X -e')?

thanks.

ok, i got one step further.

${executedProject} is injected by plexus and related to the @execute mojo
tag. adding it made the ${executedProject} available.

see also
http://www.docjar.com/docs/api/org/apache/maven/plugin/AbstractMojo.html
under execute entry.
