> When depending on Apache ODFToolkit simple-odf in my application (org.apache.odftoolkit:simple-odf:0.8.2-incubating), I observe that com.sun:tools is transitively imposed on my project as a dependency (coming from taglets, see its [POM|https://repo1.maven.org/maven2/org/apache/odftoolkit/taglets/0.8.11-incubating/taglets-0.8.11-incubating.pom]). Similarly, org.slf4j:slf4j-log4j12 is passed to my project as a dependency.
> I suspect these dependencies are actually not required for projects depending on simple-odf.
> It is possible and simple to ease the life of users of simple-odf by adding <optional> in the relevant pom files. This would respect Maven best practices. (See for example [SO|https://stackoverflow.com/questions/32231814/how-can-i-remove-logback-from-a-librarys-dependency-while-keeping-slf4j].)
> Workaround: add exclusion rules for these artifacts (see this example [POM|https://github.com/oliviercailloux/Test-ODFToolkit-ODS/blob/master/pom.xml]).
> (I tried to discuss it [here|https://lists.apache.org/thread.html/6fa4257e67ede90bac58f5518e1be41e7561a451149cbc9eecdbbf1e@%3Codf-users.incubator.apache.org%3E] but received no answer.)
