Change the execution directory of a cxf-codegen-plugin - maven

I'm building some tooling to (automatically) convert a large ANT project to a Maven structure. The project contains webservices. Therefore, I'm not able to change the input wsdl / xsd files. This is my input wsdl file. It contains a reference to a types definition from the poject base dir.
<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" targetNamespace="http://schemas.test.com/test" name="Test">
<wsdl:import namespace="http://schemas.test.com/test" location="./src/wsdl/Test.xsd"/>
<wsdl:types>
</wsdl:types>
</wsdl:definitions>
This is my maven plugin configuration:
<plugin>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-codegen-plugin</artifactId>
<executions>
<execution>
<id>generate-sources</id>
<phase>generate-sources</phase>
<goals>
<goal>wsdl2java</goal>
</goals>
<configuration>
<sourceRoot>${project.build.directory}/generated-sources/cxf</sourceRoot>
<wsdlRoot>${project.build.directory}/../src/wsdl/</wsdlRoot>
<includes>
<include>**/*.wsdl</include>
</includes>
</configuration>
</execution>
</executions>
</plugin>
Building the submodule works fine, since the cfx-codegen-plugin seems to take the ${project.basedir} as execution root directory.
However, when I try to build the complete multimodule project, the cfx-codegen-plugin seems to revert to the project.parent.basedir. I get the following build error:
Caused by : WSDLException (at /wsdl:definitions/wsdl:import): faultCode=PARSER_ERROR: Problem parsing './src/wsdl/Test.xsd'.: java.io.FileNotFoundException: C:\Users\test\Desktop\multimod\src\wsdl\Test.xsd (The system cannot find the path specified)
Does anyone know how to:
Change the execution root dir of a plugin in a specific maven phase?
Or force the cfx-codegen-plugin to use an alternative execution root?
Thanks,
sjaak

IOException thrown when processing xsd dependencies in maven

I have a problem while processing .xsd file during my maven build.
I use jaxb2 plugin but I have to download external dependiencies from my .xsd files. The problem is that these dependencies (.xsd) are from enviroment which is unstable and very often my build fails because maven cannot download xsd file. How to configure jaxb plugin to force him to try download xsd few times to prevent build failure?

Author of the maven-jaxb2-plugin here.
You have two parts here: managing the downloads of external resources and compiling the schemas, rewriting "external" links to local files.
The first (managing downloads) is not in the scope of the maven-jaxb2-plugin, the second is supported with
catalogs.
In short, you can create a catalog file like this:
REWRITE_SYSTEM "http://www.w3.org" "w3c"
Or this:
REWRITE_SYSTEM "http://schemas.opengis.net" "maven:org.jvnet.ogc:ogc-schemas:jar::!/ogc"
And use this file to "rewrite" absolute links to local files or resources within Maven artifacts:
<configuration>
<catalog>src/main/resources/catalog.cat</catalog>
</configuration>
As for the first part, I don't think managing downloads with retries, continuations and all other stuff should be in the scope of the JAXB2 Maven plugin.
ps. You don't need build-helper-maven-plugin/add-source with maven-jaxb2-plugin, source directory is added automatically.
Apparently the maven-jaxb2-plugin does not support such a feature. (And neither does the maven-download-plugin nor even the maven-dependency-plugin).
Three solutions come into my mind at the moment (plus two and a half inspired by LIttle Ancient Forest Kami's comment) [Numbers reflect the precedence of what I would do]:
Use a CI tool (Jenkins, etc.) that supports retry on job failure. [1]
Handmade:
Use the GMavenPlus plugin with a script ... [2]
Use the Maven AntRun plugin with a script ... [3]
Use the Exec Maven plugin with a program ... [5]
... that performs the download and retry and bind it to the generate-resources phase in your project's POM.
Create a Maven plugin with appropriate parameters (url, outputDirectory, retryCount) that uses the maven-download-plugin and performs the retry. Bind its goal to the generate-resources phase in your project's POM. [4]
Create a check-download Maven project that uses the maven-download-plugin bound to the generate-resources phase to download the .xsd. [6]
Create a shell script that contains the following (in pseudo code):
download:
counter++
<check-download project>/mvn generate-resources
if error and counter < maxRetryCount goto download
if not error
<your project>/mvn ...
else
display appropriate error message
There is also a question Maven download retry? from 2005. Unanswered.

Maven 2.2.1: [Warning] JAR will be empty - no content was marked for inclusion

Maven 2.2.1
JDK - 1.6.0_45
[WARNING] JAR will be empty - no content was marked for inclusion!
BUILD SUCCESSFUL
But build creates jar with pom.xml but no class files.
On the maven source code this exception is thrown only when source directory is not found.
The build is working for all other developers except on my workstation and one more workstation
I have tried all the solutions provided for this issue on stack overflow.
My source directory is src/java.
I also created src/main/java as source still no result.
I am calling mvn -o jar:jar && call mvn -o antrun:run
-o is becuase at this point I am testing with some old jars.

First follow the conventions in Maven which means your production sources code should be in src/main/java. You should also locate your resources like property files or other kind of files (like xml files) in your case to the proper location which is for production src/main/resources and for unit tests src/test/resources.
The first thing you should change is the directory structure for your project in the process in migration. That will save many hassles with configurations in Maven cause you are violating the convention over configuration paradigm.
Your unit tests code in src/test/java and follow the naming conventions for unit tests which means name your unit tests like *Test.java nothing more. You don't need to define a suite to run all the tests. If you follow the naming convention maven-surefire-plugin will do all the work for you.
Remove the antrun plugin from your pom configuration and use
mvn install
instead to install your produced jar into local repository. Based on the build life cycle you will compile, unit test and package your code into resulting jar files.
Usually in Maven there is no reason to call mvn jar:jar separately.
Apart from that all you should stop using Maven 2.2.1 cause it has defined End Of Life. Better start with Maven 3.X instead. But everything i wrote before is valid Maven 3.
I got Build Success but same error:
JAR will be empty - no content was marked for inclusion.
It was a test project and I realized that I had no "main" under "src". As soon as I corrected this, it was fixed. I am adding the wrong and right structure screenshots in the attachments:

build dependency on shared JavaScript file

Context:
We use a third-party maven plugin to compile lesscss into css
(lesscss-maven-plugin)
We cannot modify or update this plugin.
We cannot switch to another plugin, use grunt, or any other build
tool.
The plugin allows us to specify a JS file as a workaround to
upgrading the plugin itself.
Currently we have to have a copy of the
file included with each and every project
Question:
How can the JS file be packaged and a build/compile time dependency defined in the POM so that the file can be shared across projects easily?
Is it possible to use a URL for the file path instead of the {project.basedir}?
Example POM Snippet:
<plugin>
<groupId>org.lesscss</groupId>
<artifactId>lesscss-maven-plugin</artifactId>
<version>1.3.0</version>
<configuration>
<sourceDirectory>${project.basedir}/src/main/resources/less</sourceDirectory>
<outputDirectory>${project.basedir}/src/main/webapp/css</outputDirectory>
<compress>true</compress>
<includes>
<include>example.less</include>
</includes>
<lessJs>${project.basedir}/src/main/webapp/lib/less-1.7.0.min.js</lessJs>

jaxb2-maven-plugin with external XSD dependencies

We have a common set of XSDs (datatypes, vocabulary, etc.) we're generating with the jaxb2-maven-plugin in its own Maven project. In a second project, I need to refer to one or more of those XSDs at compile time but don't want them included in the resulting artifact. I've created a catalog file, which works fine except I get everything in it.
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>jaxb2-maven-plugin</artifactId>
<version>1.6</version>
<executions>
<execution>
<goals>
<goal>xjc</goal>
</goals>
</execution>
</executions>
<configuration>
<outputDirectory>${basedir}/src/main/java</outputDirectory>
<target>2.1</target>
<catalog>catalog.cat</catalog>
</configuration>
I've pored over the plugin docs, but they're woefully light on detail. Is there any way to get reuse out of common schemas without every project having to take a copy of them?
Thanks
This is something my maven-jaxb2-plugin can do:
Compiling schema from Maven Artifact
The documentation site is currently very unstable so here's snippets of the documentation.
<configuration>
<forceRegenerate>true</forceRegenerate>
<schemas>
<schema>
<dependencyResource>
<groupId>org.jvnet.jaxb2.maven2</groupId>
<artifactId>maven-jaxb2-plugin-tests-po</artifactId>
<!-- Can be defined in project dependencies or dependency management -->
<version>${project.version}</version>
<resource>purchaseorder.xsd</resource>
</dependencyResource>
</schema>
</schemas>
</configuration>
Here's a sample project.

How to compile resources folder with Maven command

I'm using mvn compile to compile my Maven webapp. This project has a resources folder instead of the java folder created for a .jar project. My problem is that mvn finds no sources, and I haven't find a way in the maven docs to proceed this way. Is there a way, either by mvn command options or by pom.xml modification to make mav aware of the resources folder and compile it?
I know changing the name from resources to java makes the deal, but that's a spureous way to proceed.
To include additional source directories in your project you can use the Build Helper Maven Plugin
So for example the following configuration will add the src/main/resources folder of your project as a source folder.
<project>
...
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>build-helper-maven-plugin</artifactId>
<version>1.8</version>
<executions>
<execution>
<id>add-source</id>
<phase>generate-sources</phase>
<goals>
<goal>add-source</goal>
</goals>
<configuration>
<sources>
<source>${basedir}/src/main/resource</source>
</sources>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
</project>
Look at your .classpath file. That should have what folders including src and test are added. You can then add additional resources. I would normally use the IDE to look at the build path and add/exclude resources.
