Spring toolsuite shows error on <execution> for maven-jaxb2-plugin

Question

I am using Spring Tool Suite version 3.7.0.RELEASE and I'm trying out an import of a WSDL offered by Amazon. The import succeeds, but Eclipse gives an error message on the tag.

I am using the following pom.xml:

<?xml version="1.0" encoding="UTF-8"?>

                    </schema>
                </schemas>
            </configuration>
        </plugin>
        <!-- end::wsdl[] -->
    </plugins>
</build>
</project>

When hovering over this tag, I get the following error message:

Execution default of goal org.jvnet.jaxb2.maven2:maven-jaxb2-plugin:0.12.3:generate failed: A required class was missing while executing org.jvnet.jaxb2.maven2:maven-jaxb2-plugin:0.12.3:generate: com/sun/xml/bind/v2/model/core/TypeInfoSet

Answer 1

I was able to fix this by putting my <plugins> inside of a <pluginManagement> tag. Somehow this makes it different for maven and it actually picks up the correct information.
