When installing the nuxeo-platform importer addon, the following message is displayed:
Installing nuxeo-platform-importer-1.7.3-SNAPSHOT Got warnings on package validation nuxeo-platform-importer-1.7.3-SNAPSHOT -> [Ignored command in installer. Source file not found! lib] Can't update using /home/nuxeo/nuxeo-server-tomcat-8.10-SNAPSHOT/packages/store/nuxeo-platform-importer-1.7.3-SNAPSHOT/install/lib. File is missing.
There is actually no lib that needs to be installed for this package, so the install.xml file should be fixed to remove:
<update file="${package.root}/install/lib" todir="${env.lib}" />
