Getting issue "Cannot resolve com.sun:tools:1.4.2" when first building maven template

[Hung Dao]

When first pulling and resolve dependency by maven, I got error
Cannot resolve com.sun:tools:1.4.2

Here is my local machine configuration

Apache Maven 3.8.1 
Maven home: /usr/local/Cellar/maven/3.8.1/libexec
Java version: 11.0.9.1, vendor: AdoptOpenJDK, runtime: /Library/Java/JavaVirtualMachines/adoptopenjdk-11.jdk/Contents/Home

Try to add exclusion for cubano dependency to fix. Not sure this is good approach to do it or not

<dependency>
            <groupId>org.concordion</groupId>
            <artifactId>cubano-concordion</artifactId>
            <version>1.1.0</version>
            <scope>test</scope>
            <exclusions>
                <exclusion>
                    <artifactId>tools</artifactId>
                    <groupId>com.sun</groupId>
                </exclusion>
            </exclusions>
        </dependency>
