No schemas to compile. Skipping XJC execution.

[titoc]

I have A.wsdl in ${project.basedir}/src/main/resources/wsdl/message and B.wsdl in my ${project.basedir}/src/main/resources/wsdl/search.

But when I do jaxb2:generate, I get the below warning and no class files are generated in the generated-sources directory.

Any help is appreciated. I followed this documentation https://github.com/highsource/maven-jaxb2-plugin/wiki/Use-Separate-Target-Directories-for-Separate-Executions

The same issues for me. And even more: It works only if configuration is placed not in execution tag but in plugin tag. And even with only one execution configuration it doesn't work:

<plugin>
    <groupId>org.jvnet.jaxb2.maven2</groupId>
    <artifactId>maven-jaxb2-plugin</artifactId>
    <version>0.15.1</version>
    <executions>
        <execution>
            <id>v20</id>
            <goals>
                <goal>generate</goal>
            </goals>
            <configuration>
                <extension>true</extension>
                <args>
                    <arg>-Xinheritance</arg>
                </args>
                <plugins>
                    <plugin>
                        <groupId>org.jvnet.jaxb2_commons</groupId>
                        <artifactId>jaxb2-basics</artifactId>
                        <version>0.12.0</version>
                    </plugin>
                </plugins>
                <schemaDirectory>src/xsd/v20</schemaDirectory>
                <generateDirectory>src/main/generated/v20</generateDirectory>
                <removeOldOutput>true</removeOldOutput>
            </configuration>
        </execution>
    </executions>
</plugin>

And this one work:

<plugin>
    <groupId>org.jvnet.jaxb2.maven2</groupId>
    <artifactId>maven-jaxb2-plugin</artifactId>
    <version>0.15.1</version>
    <executions>
        <execution>
            <id>v20</id>
            <goals>
                <goal>generate</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <extension>true</extension>
        <args>
            <arg>-Xinheritance</arg>
        </args>
        <plugins>
            <plugin>
                <groupId>org.jvnet.jaxb2_commons</groupId>
                <artifactId>jaxb2-basics</artifactId>
                <version>0.12.0</version>
            </plugin>
        </plugins>
        <schemaDirectory>src/xsd/v20</schemaDirectory>
        <generateDirectory>src/main/generated/v20</generateDirectory>
        <removeOldOutput>true</removeOldOutput>
    </configuration>
</plugin>

Same for me. The generation only works if the configuration is set in the plugin tag.

Check #251 and (soon to be released) 0.15.2.

I updated to newer JAXB 2.3.7 which has some wsdl fixes and reworked jaxb dependencies (esp w/ xjc)

Thanks for your reply, I've checked my project with new version but nothing has changed for me.
Here is minimum example of my issue:
MavenXJC.zip
Two pom files. pom.xml is what I want and it doesn't work and pom_good.xml works

[LegendaryZer0]

Has anyone found a way to fix it yet? Upgrading the version didn't work for me.

UPD: Worked for me with 11 jdk version

Thanks @HeavyS for your sample. We'll try to work on it if latest 2.0.2 version didn't do the job.
Did you also try to specify schemaLanguage tag to wsdl in config since, from what I've seen, you try to generate wsdl files ?

[laurentschoelens]

Hi @HeavyS and everyone (@LegendaryZer0 / @titoc / @stessy).
I've tested your project example and reproduced your issue with jdk8 and success with jdk11 without changing the pom
The good news is : version 2.0.2 fixed your issue with jdk8

You can use the following (new) version since groupId / artifactId changed from v2.

<groupId>org.jvnet.jaxb</groupId>
<artifactId>jaxb-maven-plugin</artifactId>
<version>2.0.2</version>

I'm adding a test project (jt-250) in 2.0.3 to keep this issue under control

[laurentschoelens]

Test has been added in 2.0.4 release
