jaxb, xsd import not recognized

Question

I have a big problem with jaxb plugin. I have a project A where I have src/main/resources/xsd/common.xsd file. In this project I use cxf-xjc-plugin to generate java classes. I have also my episod file under src/main/resources/META-INF called sun-jaxb.episode

Next, I have project B which has maven dependency to project A. In this project I have src/main/resources/catalog.txt

PUBLIC "http://www.some_path" "maven:GROUP_ID_OF_PROJECT_A:ARTIFACT_ID_OF_PROJECT_A:jar::!/common.xsd"

In project B I have pom file with jaxb plugin

<plugin>
            <groupId>org.jvnet.jaxb2.maven2</groupId>
            <artifactId>maven-jaxb2-plugin</artifactId>
            <configuration>
                <extension>true</extension>
                <episodes>
                    <episode>
                        <groupId>GROUP_ID_OF_PROJECT_A</groupId>
                        <artifactId>ARTIFACT_ID_OF_PROJECT_A</artifactId>
                    </episode>
                </episodes>
                <catalogs>
                    <catalog>src/main/resources/catalog.txt</catalog>
                </catalogs>
            </configuration>
 </plugin>

Next, I have in project B

 src/main/resources/other/xsd my main.xsd

file where I use type definitions from common.xsd

I have xmlns:cmns="http://www.some_path" // it is the same as in catalog.txt and

<xs:import namespace="http://www.some_path"/>

but the problem is that I get error undefined simple or complex type , because it doesn't recognize cmns

You must perform a mvn install of project A before the project B

Add this plugin to add to source target generated classes

          <plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>build-helper-maven-plugin</artifactId>
                <version>1.1</version>
                <executions>
                    <execution>
                        <id>add-source</id>
                        <phase>generate-sources</phase>
                        <goals>
                            <goal>add-source</goal>
                        </goals>
                        <configuration>
                            <sources>
                                <source>target/generated-sources/xjc</source>
                            </sources>
                        </configuration>
                    </execution>
                </executions>
            </plugin>

Remember to perform Maven - update project

+1 for using the official JAXB plugin. https://jaxb.java.net/ https://java.net/projects/maven-jaxb2-plugin/pages/Home — Puce, Sep 24 '14 at 08:04
Strange, i work in an architecture complex based on this plugin. See this [link](http://confluence.highsource.org/display/MJIIP/User+Guide#UserGuide-Separateschemacompilation) to separate compilation and [this](http://confluence.highsource.org/display/MJIIP/User+Guide#UserGuide-Resourceentries) to refer a resource. — Xstian, Sep 24 '14 at 08:24
@Puce I am the author of the `maven-jaxb2-plugin` you mention. To be clear, this is NOT an "official" JAXB plugin. I am not an Oracle employee and not affiliated. — lexicore, Sep 24 '14 at 09:15
It turns out that I can use in my main.xsd, but episod file seems to be ignored and common classes are generated twice ( in project A and B) — Unyx, Sep 24 '14 at 09:34
You must remove schemaLocation="common.xsd" else identify as local source — Xstian, Sep 24 '14 at 09:39
@lexicore thanks for the clarifiaction. But at least it's the only one Maven plugin mentioned on the official JAXB homepage: https://jaxb.java.net/ — Puce, Sep 24 '14 at 09:42
It generates now, but in target folder. Can I specify it to generate in src/main/generated? — Unyx, Sep 24 '14 at 11:09
I added src/main/generated/ but it still generate in target folder — Unyx, Sep 24 '14 at 11:18
You should only copy build-helper-maven-plugin this plugin in your pom.xml (below my answer).. Let me know — Xstian, Sep 24 '14 at 11:21
? I have this one maven-jaxb2-plugin . Why should I have another plugin with the same executions etc — Unyx, Sep 24 '14 at 11:25
The second one adds the classes generated to source. You need of this to work fine everything and use the generated classes. — Xstian, Sep 24 '14 at 11:26
Have you perform a maven update project? .. as i say in my answer — Xstian, Sep 24 '14 at 11:31
now it created target/generated-sourcex/xjc but I wanted something different. I have src/main/generated and I want that thse generated classes will be placed there, but when I specify src/main/generated it still create target/generated.. — Unyx, Sep 24 '14 at 11:39
See the guide of that plugin [here](http://confluence.highsource.org/display/MJIIP/User+Guide). is that you needed. Anyway the topic is solved, you were able to resolve all by maven plugins. — Xstian, Sep 24 '14 at 12:02
