Error building maven multi module project with frontend-maven-plugin

Question

I am following this tutorial to build a project with Spring Boot backend and Angular frontend.

The only changes I made are the versions in the web project .pom:

<plugin>
            <groupId>com.github.eirslett</groupId>
            <artifactId>frontend-maven-plugin</artifactId>
            <version>1.7.5</version>
            <configuration>
                <nodeVersion>v10.14.1</nodeVersion>
                <npmVersion>6.8.0</npmVersion>
                <workingDirectory>src/main/web/</workingDirectory>
            </configuration>
...

The error I got is this:

I have seen that this is a somewhat common error but I cannot find a solution that works for me.

I've tried changing the maven version (used: 3.0.4 but 3.1 and above was needed, 3.2.5, 3.3.3 bundled with IntelliJ and latest 3.6.0)

I messed around with the frontend-maven-plugin version using 1.3, 1.6, 1.7.5.

I added jackson-mapper-asl and jackson-core-asl 1.9.13 dependencies on the project, still nothing.

I was deleting .m2\\repository\\com\\github folder throughout the above changes.

Nothing worked so far.

Please help, thanks in advance.

Answer 1

The problem was in the frontend-maven-plugin itself.

I managed to run my code by executing the following steps:

1. I cloned the master branch from their github repository to my machine.

2. There is an import error in the NPMInstaller.java class file. I replaced the

   import org.codehaus.jackson.map.ObjectMapper;

with

import com.fasterxml.jackson.databind.ObjectMapper;

and added the dependency in the pom.xml:

    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-databind</artifactId>
        <version>2.9.6</version>
    </dependency>

3. I tried to build it but got some problems with maven-javadoc-plugin so I commented every entry I found in the project poms.
4. mvn clean install the root project. This created a 1.7.6-SNAPSHOT folder in my .m2 directory.
5. Altered the plugin version in my project to 1.7.6-SNAPSHOT and everything works fine.
