It will work for ordinary shapshots, but not for parent snapshots. Try changing the parent version of a pom to 99-SNAPSHOT and see what happens. (Deliberately using a non-existent version so it won't be found locally) For me this fails with: $ mvn clean [ERROR] [ERROR] Some problems were encountered while processing the POMs: [FATAL] Non-resolvable parent POM for org.apache.commons:commons-compress:1.16-SNAPSHOT: Could not find artifact org.apache.commons:commons-parent:pom:99-SNAPSHOT and 'parent.relativePath' points at wrong local POM @ line 20, column 11 Note that it does not attempt a download. Whereas if I use -Psnapshotrepo I get $ mvn clean -Psnapshotrepo [INFO] Scanning for projects... Downloading: https://repository.apache.org/content/repositories/snapshots/org/apache/commons/commons-parent/99-SNAPSHOT/maven-metadata.xml Downloading: https://repository.apache.org/content/repositories/snapshots/org/apache/commons/commons-parent/99-SNAPSHOT/commons-parent-99-SNAPSHOT.pom [ERROR] [ERROR] Some problems were encountered while processing the POMs: [FATAL] Non-resolvable parent POM for org.apache.commons:commons-compress:1.16-SNAPSHOT: Could not find artifact org.apache.commons:commons-parent:pom:99-SNAPSHOT in apache.snapshots.https (https://repository.apache.org/content/repositories/snapshots) and 'parent.relativePath' points at wrong local POM @ line 20, column 11 i.e. it tries to download the pom but fails. This shows that the snapshot repo has now been defined, as expected. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@commons.apache.org For additional commands, e-mail: dev-h...@commons.apache.org
