Check if a maven artifact exists. Designed around the use case of skipping deployment if the stable version already exists.
Mojo details at plugin info
Two basic goals: local checks if the just built artifact is already in the local repository; and remote checks if the just built artifact is already in the remote repository.
| Parameter | Default | Description |
|---|---|---|
| project | ${project.groupId}:${project.artifactId}:${project.version} | The project within the repository to query |
| artifact | ${project.artifactId}-${project.version}.{packaging} | The artifact within the project to query |
| property | maven.deploy.skip | The property to receive the result of the query |
| userProperty | false | If the property should be set as a user property, to be available in child projects |
| useChecksum | ${createChecksum} | Use checksum to compare artifacts (Checksums only available when install plugin is so configured.) |
| skipIfSnapshot | true | If checksums are not used, skip the query if the project ends with -SNAPSHOT |
| repository | ${project.distributionManagement.repository.url} | For remote goal, the repository to query for artifacts |
| snapshotRepository | ${project.distributionManagement.snapshotRepository.url} | For remote goal, the repository to query for snapshot artifacts |
| serverId | ${project.distributionManagement.repository.id} | For remote goal, the server ID to use for authentication and proxy settings |
| snapshotServerId | ${project.distributionManagement.snapshotRepository.id} | For remote goal, the server ID to use for snapshot authentication and proxy settings |
| failIfExists | ${failIfExists} | Fail the build if the artifact already exists |
| failIfNotExists | ${failIfNotExists} | Fail the build if the artifact does not exist |
