There's this task:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.6</version>
<executions>
<execution>
<id>clean</id>
<phase>clean</phase>
<configuration>
<tasks>
<delete dir="src\test\resources\templates" includeemptydirs="true" />
</tasks>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
The problem is: when I run mvn clean, <phase>clean</phase> tells maven to download project dependencies (that don't exist yet) and I get Could not resolve dependencies error.
How to tell maven not to require project dependencies to run this plugin?

I would like to know if it is possible to resolve the path for a maven artifact without having this artifact as a dependency in the project?
What I am trying to do is to execute an external java code generator via exec-maven-plugin or maven-antrun-plugin:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>3.0.0</version>
<configuration>
<executable>java</executable>
<arguments>
<argument>-jar ${de.powerstat.fb:generator:1.0-SNAPSHOT}</argument>
<argument>de.powerstat.fb.generator.CodeGenerator</argument>
<argument>${fb.hostname}</argument>
<argument>${fb.port}</argument>
<argument>${fb.username}</argument>
<argument>${fb.password}</argument>
<argument>${project.build.directory}</argument>
</arguments>
</configuration>
<executions>
<execution>
<phase>generate-sources</phase>
<goals>
<goal>exec</goal>
</goals>
</execution>
</executions>
</plugin>
So the point here is how to solve the jars path for ${de.powerstat.fb:generator:1.0-SNAPSHOT} without having it as a dependency of the whole project? Also using the exec:java goal is not a solution, because this one seems to have different problems, but thats another question.
Using the antrun plugin I come to the same problem:
<plugin>
<artifactId>maven-antrun-plugin</artifactId>
<version>3.0.0</version>
<executions>
<execution>
<phase>generate-sources</phase>
<configuration>
<target>
<java fork="true" failonerror="true" module="de.powerstat.fb.generator" modulepath="${de.powerstat.fb:generator:1.0-SNAPSHOT}">
<arg value="${fb.hostname} ${fb.port} ${fb.username} ${fb.password} ${project.build.directory}"/>
</java>
</target>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
So question is again how to solve the modulepath="${de.powerstat.fb:generator:1.0-SNAPSHOT}"?
Solutions that use the maven dependency plugin with the goal dependency:properties will not work in this scenario.
I suggest to use dependency:copy to copy the JAR to some place in /target. Then you can add that path to the antrun or exec plugin.
I have the following pom config. I added the cobertura plugin, and now pmd, cpd, findbugs, and test are running twice.
I understand that is because of my "phases" config, but I don't understand how can I achieve the following:
What I want is before I commit to the repo, build my app and check for pmd errors, findbugs errors, check my tests, and check my cobertura.
How can I achieve this? I am used to run "mvn clean package" before commit. It's that ok?
Here's my config:
...

Any maven plugin has a default execution phase. In this case, the plugins that you apply are executed in the verify phase (pmd-plugin). But you are defining it to run also in the compile phase. Removes the phase tag and lets it run in the verification phase.
<execution>
<!--<phase>compile</phase>-->
<goals>
<goal>...</goal>
...
</goals>
</execution>
Finally, the good practice to validate your project before a commit is to run:
mvn clean verify
am trying to build a parent pom in Maven which includes a child which is built in ant. I am getting the below exception,
Execution default of goal org.apache.maven.plugins:maven-antrun-plugin:1.6:run failed: A required class was missing while executing org.apache.maven.plugins:maven-antrun-plugin:1.6:run
My code is:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.6</version>
<executions>
<execution>
<phase>compile</phase>
<configuration>
<target>
<ant dir="SampleJava/projectBuilder.xml" />
</target>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
and it got resolved with the below code:
--------
<plugin>
<artifactId>maven-antrun-plugin</artifactId>
<executions>
<execution>
<phase>process-resources</phase>
<configuration>
<tasks>
<ant antfile="../SampleJava/projectBuilder.xml" target="makejar"/>
</tasks>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
I'm wondering if there is a way to enforce the existence of a dependency to unpack when using the dependency-unpack goal of the maven dependency plugin. I'm using the configuration below and the problem is that if there is no dependency specified for "${properties.artifactId}" in the dependencies section of the pom the build goes ahead even though nothing has been unpacked. It invariably fails later at the test stage but it would be so much easier if the build could fail when no dependency is present. So does anyone know of a way that this can be enforced?
Thanks

A couple of executions of the maven-enforcer-plugin should do it. You need one to run before the dependency plugin, to make sure ${properties.artifactId} has a value, then another that runs after the dependency plugin to make sure there are files in the target location. Here's the idea, modify for your requirements.
You may write your own rules too if those available don't quite fit.

I am trying to include the build number in the pdf's that get generated with the maven pdf plugin. I have all the documentation of the project I am working on written as a maven site. This way all the documentation is stored with the source code.
Pom.xml
So in the pom.xml I have defined the buildnumber plugin:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>buildnumber-maven-plugin</artifactId>
<version>1.2</version>
<executions>
<execution>
<phase>generate-resources</phase>
<goals>
<goal>create</goal>
</goals>
</execution>
</executions>
<configuration>
<doCheck>false</doCheck>
<doUpdate>false</doUpdate>
<format>{0,date,yyyy-MM-dd_HH-mm}_{1}</format>
<items>
<item>timestamp</item>
<item>${user.name}</item>
</items>
</configuration>
</plugin>
pdf.xml
And in the pdf.xml
<cover>
<coverTitle>${project.name}</coverTitle>
<coverSubTitle>v. ${project.version}</coverSubTitle>
<coverType>Technical documentation</coverType>
<coverVersion>build: ${project.buildNumber}</coverVersion>
<projectName>${project.name}</projectName>
<projectLogo>images/telfortlogo.jpg</projectLogo>
</cover>
I even put resource filtering to ${basedir}/site but it has no effect. I keep getting the ${buildNumber} instead of the result of the buildnumber plugin.
To get something similar working my buildnumber plugin configuration looked like this:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>buildnumber-maven-plugin</artifactId>
<version>1.2</version>
<executions>
<execution>
<phase>pre-site</phase>
<goals>
<goal>create</goal>
</goals>
<configuration>
<doCheck>false</doCheck>
<doUpdate>false</doUpdate>
<format>{0,date,yyyy-MM-dd_HH-mm}_{1}</format>
<items>
<item>timestamp</item>
<item>${user.name}</item>
</items>
</configuration>
</execution>
</executions>
</plugin>
And in the pdf.xml:
<cover>
<coverTitle>${project.name}</coverTitle>
<coverSubTitle>v. ${project.version} build ${buildNumber}</coverSubTitle>
<coverType>User Guide</coverType>
<projectName>${project.name}</projectName>
</cover>
I believe that your issue comes from the fact that you are executing the buildnumber create goal during the generate-resources phase. And if you are using mvn pdf:pdf or mvn site, the generate-resources will not get executed.
I my setup I have configured the pdf plugin to run on the site phase:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-pdf-plugin</artifactId>
<executions>
<execution>
<id>pdf</id>
<phase>site</phase>
<goals>
<goal>pdf</goal>
</goals>
I can then get the pdf to be generated at the end of the site phase.
