Any idea whats going on?

Solution

  • Ok i found out that the solution to this is that in frontend-maven-plugin configuration you have to specify workingDirectory and installDirectory. So in my case the plugin definiton in pom.xml will look like this:

    <plugin>
                <groupId>com.github.eirslett</groupId>
                <artifactId>frontend-maven-plugin</artifactId>
                <version>1.9.1</version>
                <configuration>
                    <nodeVersion>v12.16.3</nodeVersion>
                    <workingDirectory>client</workingDirectory>
                    <installDirectory>target</installDirectory>
                </configuration>
                <executions>
                    <execution>
                        <id>install-npm</id>
                        <goals>
                            <goal>install-node-and-npm</goal>
                        </goals>
                    </execution>
                    <execution>
                        <id>npm-install</id>
                        <goals>
                            <goal>npm</goal>
                        </goals>
                    </execution>
                    <execution>
                        <id>npm run build</id>
                        <goals>
                            <goal>npm</goal>
                        </goals>
                        <configuration>
                            <arguments>run build</arguments>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
