I have tried to use jsonix-schema-compiler according to https://github.com/highsource/jsonix-schema-compiler/wiki/Maven-Usage but it doesn't work
I have even tried to specify other arguments as follows:
<build>
<finalName>test-json</finalName>
<plugins>
<plugin>
<groupId>org.jvnet.jaxb2.maven2</groupId>
<artifactId>maven-jaxb2-plugin</artifactId>
<version>0.13.1</version>
<executions>
<execution>
<goals>
<goal>generate</goal>
</goals>
<configuration>
<extension>true</extension>
<args>
<arg>-Xjsonix</arg>
<arg>-generateJsonSchema</arg>
<arg>-d</arg>
<arg>${basedir}/target/generated-sources/</arg>
<arg>-b</arg>
<arg>${basedir}/src/main/resources/xsd/jaxb_bindings.xjb</arg>
<arg>-p</arg>
<arg>CustomerJSON</arg>
<arg>-Xjsonix-logLevel</arg>
<arg>TRACE</arg>
<arg>${basedir}/src/main/resources/xsd/Customer.xsd</arg>
</args>
<plugins>
<plugin>
<groupId>org.hisrc.jsonix</groupId>
<artifactId>jsonix-schema-compiler</artifactId>
<version>${jsonix-schema-compiler.version}</version>
</plugin>
</plugins>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
but nothing changes and all what I get is [WARNING] No schemas to compile. Skipping XJC execution. as can be seen in the following logs

So what is the good configurations for jsonix-schema-compiler?
You shouldn't "mirror" your command-line XJC/Jsonix Schema Compiler usage in Maven config. It works much more with convention over configuration.
So just put your schemas and binding files in src/main/resourcesand then just turn on Jsonix XJC plugin with -Xjsonix:
<build>
<finalName>test-json</finalName>
<plugins>
<plugin>
<groupId>org.jvnet.jaxb2.maven2</groupId>
<artifactId>maven-jaxb2-plugin</artifactId>
<version>0.13.1</version>
<executions>
<execution>
<goals>
<goal>generate</goal>
</goals>
<configuration>
<extension>true</extension>
<args>
<arg>-Xjsonix</arg>
<arg>-Xjsonix-generateJsonSchema</arg>
</args>
<plugins>
<plugin>
<groupId>org.hisrc.jsonix</groupId>
<artifactId>jsonix-schema-compiler</artifactId>
<version>${jsonix-schema-compiler.version}</version>
</plugin>
</plugins>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
If you actually want to reconfigure source and target directories and so on, check maven-jaxb2-plugin configuration (see the cheat sheet, for instance). Specifically, for the configuration you'll probably need:
schemaDirectorybindingDirectorygeneratePackage - not recommended for usage, specify packages and module names in binding files instead, see this
