missing dependency when building mule sample

[olensmar]

When trying to build master I get

[ERROR] Failed to execute goal on project swagger-java-mule-app: Could not resolve dependencies for project io.swagger:swagger-java-mule-app:mule:1.0.0: The following artifacts could not be resolved: javax.activation:activation:jar:1.1-osgi, org.apache.geronimo.specs:geronimo-j2ee-connector_1.5_spec:jar:1.1-osgi, dom4j:dom4j:jar:1.6.1-osgi, commons-codec:commons-codec:jar:1.3-osgi, commons-httpclient:commons-httpclient:jar:3.1-osgi, commons-jxpath:commons-jxpath:jar:1.3-osgi, xpp3:xpp3_min:jar:1.1.3.4.O-osgi, net.java.dev.stax-utils:stax-utils:jar:20080702-osgi, net.sf.saxon:saxon:jar:8.9.0.4-osgi, net.sf.saxon:saxon-dom:jar:8.9.0.4-osgi, net.sf.saxon:saxon-xqj:jar:8.9.0.4: Could not find artifact javax.activation:activation:jar:1.1-osgi in central (https://repo.maven.apache.org/maven2) -> [Help 1]
