$ mvn -o verify ... [ERROR] Failed to execute goal org.apache.maven.plugins:maven-checkstyle-plugin:3.1.1:check (default) on project redisson: Execution default of goal org.apache.maven.plugins:maven-checkstyle-plugin:3.1.1:check failed: Plugin org.apache.maven.plugins:maven-checkstyle-plugin:3.1.1 or one of its dependencies could not be resolved: Failed to collect dependencies at org.apache.maven.plugins:maven-checkstyle-plugin:jar:3.1.1 -> com.puppycrawl.tools:checkstyle:jar:[8.18,): No versions available for com.puppycrawl.tools:checkstyle:jar:[8.18,) within specified range -> [Help 1] Note, usual dependencies were resolved otherwise (when building dependency tree), that's why compilation succeeded in the offline mode. Full reproduction steps: git clone https://github.com/redisson/redisson.git cd redisson # to be sure we speak of the same version: git checkout 2a507699c3208e6856b6fb0f67a8b921718f7945 # in case you accidentially already have some version of checkstyle.jar # that will make the case behave differently: rm -r ~/.m2/repository/com/puppycrawl/tools/checkstyle/ mvn org.apache.maven.plugins:maven-dependency-plugin:3.1.2:tree mvn org.apache.maven.plugins:maven-dependency-plugin:3.1.2:resolve-plugins mvn -o verify So it seems the dependency:resolve-plugins uses different algorithm for dependency resolution than is used during real build. BTW, the same can be said about the dependency:resolve / dependency:go-offline mojos. I have two project that I can build successsfully, successfully generate dependency tree. But dependency:resolve / dependency:go-offline fail for them (one of those projects is the above used redisson, try dependency:resolve on it). Interestingly, if I remove the -o flag, the build log has this: Downloading: https://repo.maven.apache.org/maven2/com/puppycrawl/tools/checkstyle/maven-metadata.xml Downloading:
