Question

in my pom.xml I’ve configured maven-jaxb-plugin but I’m getting a “A required plugin was not found: Plugin could not be found – check that the goal name is correct: Unable to download the artifact from any repository” because of it. My config is like this:

<plugin>
    <groupId>com.sun.tools.xjc.maven2</groupId>
    <artifactId>maven-jaxb-plugin</artifactId>
    <version>1.1</version>
    <executions>
        <execution>
            <phase>generate-sources</phase>
            <goals>
                <goal>generate</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <generate-package>tld.mycompany.myproject.data.ws-schema</generate-package>
        <schemaDirectory>src/main/resources/ws/xsd</schemaDirectory>
    </configuration>
</plugin>

In dependencies, I have added the following.

<dependency>
    <groupId>maven-plugins</groupId>
    <artifactId>maven-jaxb-plugin</artifactId>
    <version>1.1.0</version>
</dependency>
<dependency>
  <groupId>org.jvnet.jaxb2.maven2</groupId>
  <artifactId>maven-jaxb2-plugin</artifactId>
  <version>0.7.5</version>
</dependency>
<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.2</version>
</dependency>
<dependency>
    <groupId>com.sun.xml.bind</groupId>
    <artifactId>jaxb-xjc</artifactId>
    <version>2.2</version>
</dependency>
<dependency>
    <groupId>com.sun.xml.bind</groupId>
    <artifactId>jaxb-impl</artifactId>
    <version>2.2</version>
</dependency>

What am I missing? Why can’t it find the correct artifacts?

Cheers

I suggest you use, when facing such a problem, one of the available maven search engines :

• mvnbrowser
• jarvana
• mvnrepository

the two first having my preference. Here is what they say about your artifacts :

• maven-jaxb-plugin is available at Apache
• maven-jaxb2-plugin 0.7.5 is not known. The most up-to-date version, is 0.7.3 on mvnbrowser and 0.7.4 on jarvana. which may be the reason why your maven build is broken
• jaxb-api 2.2 is available at both JavaNet and JBoss repositories

Well, wion’t do all the job for you, as I guess you get the picture now.
