Trouble with mojo tutorial
I'm trying to follow the instructions at
http://maven.apache.org/guides/plugin/guide-java-plugin-development.html.
Below are the results.
Am I experiencing some problem with the public maven repositories or is this
a bug in maven 2.0.7? (Or did I do something wrong?)
What would be the wget command to get maven-archetype-creator:jar as the
error message suggests?
Thanks,
Siegfried

Re: Trouble with mojo tutorial
Posted by Wayne Fay <wa...@gmail.com>.
I think we're talking past each other here.
I don't believe you can USE a plugin in the same pom you're using to
BUILD the plugin.
You need to REMOVE the <plugin> node in the pom, run "mvn install",
then make another pom/project and USE the plugin there.

RE: Trouble with mojo tutorial
Posted by siegfried <si...@heintze.com>.
That worked! Thanks! Can someone make changes to the tutorial on the website
with the directions below? I'd be glad to if someone gives me the password.
Thanks,

Subject: Re: Trouble with mojo tutorial
Hi,
perhaps it would be better if you would start from scratch, to have a
clean state.
Then just do this:
1.
mvn archetype:create \
-DgroupId=sample.plugin \
-DartifactId=maven-hello-plugin \
-DarchetypeGroupId=org.apache.maven.archetypes \
-DarchetypeArtifactId=maven-archetype-mojo
This will generate a simple plugin project with a sample mojo.
2.
Add the 'GreetingsMojo.java' to 'src/main/java/sample/plugin'
3.
Do an 'mvn install'.
4.
Now you can use the plugin from every maven project by executing:
mvn sample.plugin:maven-hello-plugin:1.0-SNAPSHOT:sayhi
There is no need to specify the hello-plugin in the <build/><plugins/>
section of a pom unless you want it to execute automatically during a
build or lock its version.
You may also want to read the chapters on plugin development in the two
maven books [1], [2],

Re: Trouble with mojo tutorial
Posted by Tim Kettler <ti...@udo.edu>.
Hi,
perhaps it would be better if you would start from scratch, to have a
clean state.
Then just do this:
1.
mvn archetype:create \
-DgroupId=sample.plugin \
-DartifactId=maven-hello-plugin \
-DarchetypeGroupId=org.apache.maven.archetypes \
-DarchetypeArtifactId=maven-archetype-mojo
This will generate a simple plugin project with a sample mojo.
2.
Add the 'GreetingsMojo.java' to 'src/main/java/sample/plugin'
3.
Do an 'mvn install'.
4.
Now you can use the plugin from every maven project by executing:
mvn sample.plugin:maven-hello-plugin:1.0-SNAPSHOT:sayhi
There is no need to specify the hello-plugin in the <build/><plugins/>
section of a pom unless you want it to execute automatically during a
build or lock its version.
You may also want to read the chapters on plugin development in the two
maven books [1], [2],

RE: Trouble with mojo tutorial
Posted by siegfried <si...@heintze.com>.
Thanks Wayne.
I tried that but no luck! The tutorial does not specify where to put
c:/dev/sandboxes/maven/sample-mojo/maven-hello-plugin/src/main/java/sample/p
lugin/GreetingMojo.java. I suspect I don't have this in the correct
directory. Since I did the steps out of order, I already had a
src/main/java/sample/plugin directory which looked like a logical place to
put GreetingMojo.java. Where is the pom.xml in the tutorial looking for
GreetingMojo.java?
Thanks,
Siegfried

RE: Trouble with mojo tutorial
Posted by siegfried <si...@heintze.com>.
Thanks Wayne, that "-U" appeared to work.
Now I started out the tutorial with the command
mvn -U archetype:create \
-DgroupId=sample.plugin \
-DartifactId=maven-hello-plugin \
-DarchetypeGroupId=org.apache.maven.archetypes \
-DarchetypeArtifactId=maven-archetype-mojo
because the tutorial did not tell you where to place the files pom.xml and
GreetingMojo.java. So I just put GreetingMojo down in the directly with the
other java source code. Then I clobbered the pom.xml file with pom.xml from
http://maven.apache.org/guides/plugin/guide-java-plugin-development.html.
Below is my pom.xml which I copied from
http://maven.apache.org/guides/plugin/guide-java-plugin-development.html .
Below that are the results when I try to "mvn
sample.plugin:maven-hello-plugin:1.0-SNAPSHOT:sayhi" as per the
instructions.
What am I doing wrong? I am not seeing "Hello, World".
I believe I have copied the
c:/dev/sandboxes/maven/sample-mojo/maven-hello-plugin/src/main/java/sample/p
lugin/GreetingMojo.java correctly from that web page.
So then when I realized that I executed the command " mvn -U
archetype:create... " too soon and tried moving GreetingMojo.java to
c:/dev/sandboxes/maven/sample-mojo/maven-hello-plugin/GreetingMojo.java and
running the command again but that did not help.
Thanks,
Siegfried
