Olivier Cailloux created ODFTOOLKIT-464:
-------------------------------------------
Summary: Pom does not follow best practices: missing optional
keyword
Key: ODFTOOLKIT-464
URL: https://issues.apache.org/jira/browse/ODFTOOLKIT-464
Project: ODF Toolkit
Issue Type: Bug
Components: simple api
Reporter: Olivier Cailloux
Priority: Minor
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
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 on 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
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
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.)
