I am adapting the exercise of the book "Java 9 - Interactive, reactive and modularized - author Rodrigo Turini" to a modular Maven project with java 10 modular. However this gives error when compiling the second module (http)

Each project has its module-info.java Goes below.

module-info Domain

module domain {
    exports br.com.casadocodigo.domain;
}

module-info http

module http {
    exports br.com.casadocodigo.http;

    requires domain;
    requires jdk.incubator.httpclient;
}

module-info nf

module nf {
    exports br.com.casadocodigo.service;
    exports br.com.casadocodigo.model;

    requires domain;
}

module-info app

module app {
    exports br.com.casadocodigo;

    requires domain;
    requires http;
    requires nf;
}

continues

For those who want to see the code in full, the same is in my github https://github.com/marcelosartor/Estudo-Java10_Modular-Com-Maven_Modular

The plugin maven-compiler-plugin uses the library ASM, but only the most current versions can interpret bytecode of version 10.

The central POM shall be modified with the following configuration:

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>${maven-compiler-pluging.version}</version>
                <configuration>
                    <source>10</source>
                    <target>10</target>
                    <showWarnings>true</showWarnings>
                    <showDeprecation>true</showDeprecation>
                </configuration>
                <dependencies>
                    <dependency>
                        <groupId>org.ow2.asm</groupId>
                        <artifactId>asm</artifactId>
                        <version>6.1.1</version> 
                    </dependency>
                </dependencies>
            </plugin>
  • This dependency solves my build problem. See if you can still help me. When running I have the following error. Exception in thread "main" java.lang.Noclassdeffounderror: br/com/casadocodigo/http/Books at br.com.casadocodigo.MainMavenModulo.main(Mainmavenmodulo.java:16) Caused by: java.lang.Classnotfoundexception: br.com.casadocodigo.http.Books at

  • Ask another question with this new problem, I can take a look. ;)
