Nexus Groovy scripting

Huge issue in Nexus is that you can't export/import your Users/Groups/Privileges and Repository configuration. All you can do is to take a "backup", which ends of in a folder as a completely unreadable/unversionable format.

So I was looking for

when you run a Groovy script in Nexus, you have available a predefined variable "repository", which is of type org.sonatype.nexus.script.plugin.internal.provisioning.RepositoryApiImpl

This in turn contains a reference to a blobStoreManager org.sonatype.nexus.blobstore.api.BlobStoreManager and to a repositoryManager org.sonatype.nexus.repository.manager.RepositoryManager , plus a series of convenience methods to create commonly used repository formats (you are not expected to create anything fancy, most properties are assigned by default) and groups.

Key element is a org.sonatype.nexus.repository.config.Configuration object, again very disappointing since the configuration is represented by a "attribute" map (String, Map(String, Object)) which is really a stupid idea, too generic interface.

RepositoryManager has a Iterable<Repository> browse(); which returns a collection of org.sonatype.nexus.repository.Repository

Sample script:

import org.sonatype.nexus.repository.Repository

repository.repositoryManager.browse().each { Repository repo ->
    log.info("Repository: $repo")
    log.info("Repository Configuration: $repo.configuration")
}

this dumps in nexus.log the following content:

Repository: RepositoryImpl$$EnhancerByGuice$$c5f0822b{type=proxy, format=nuget, name='nuget.org-proxy'}
Repository Configuration: Configuration{repositoryName='nuget.org-proxy', recipeName='nuget-proxy', attributes={proxy={strictContentTypeValidation=true, contentMaxAge=1440, remoteUrl=https://www.nuget.org/api/v2/, metadataMaxAge=1440}, negativeCache={}, storage={blobStoreName=default}, nugetProxy={}, httpclient={connection={blocked=false, autoBlock=true}}}}

Repository: RepositoryImpl$$EnhancerByGuice$$c5f0822b{type=hosted, format=maven2, name='maven-releases'}
Repository Configuration: Configuration{repositoryName='maven-releases', recipeName='maven2-hosted', attributes={maven={versionPolicy=RELEASE, layoutPolicy=STRICT}, storage={writePolicy=ALLOW_ONCE, strictContentTypeValidation=false, blobStoreName=default}}}

Repository: RepositoryImpl$$EnhancerByGuice$$c5f0822b{type=hosted, format=maven2, name='maven-snapshots'}
Repository Configuration: Configuration{repositoryName='maven-snapshots', recipeName='maven2-hosted', attributes={maven={versionPolicy=SNAPSHOT, layoutPolicy=STRICT}, storage={writePolicy=ALLOW, strictContentTypeValidation=false, blobStoreName=default}}}

Repository: RepositoryImpl$$EnhancerByGuice$$c5f0822b{type=proxy, format=maven2, name='maven-central'}
Repository Configuration: Configuration{repositoryName='maven-central', recipeName='maven2-proxy', attributes={proxy={contentMaxAge=-1, remoteUrl=https://repo1.maven.org/maven2/, metadataMaxAge=1440}, negativeCache={timeToLive=1440, enabled=true}, storage={strictContentTypeValidation=false, blobStoreName=default}, maven-indexer={}, httpclient={connection={blocked=false, autoBlock=true}}, maven={versionPolicy=RELEASE, layoutPolicy=PERMISSIVE}}}

Repository: RepositoryImpl$$EnhancerByGuice$$c5f0822b{type=group, format=nuget, name='nuget-group'}
Repository Configuration: Configuration{repositoryName='nuget-group', recipeName='nuget-group', attributes={storage={blobStoreName=default}, nugetProxy={}, httpclient={}, group={memberNames=[nuget-hosted, nuget.org-proxy]}}}

Repository: RepositoryImpl$$EnhancerByGuice$$c5f0822b{type=hosted, format=nuget, name='nuget-hosted'}
Repository Configuration: Configuration{repositoryName='nuget-hosted', recipeName='nuget-hosted', attributes={storage={writePolicy=ALLOW, blobStoreName=default}}}

Repository: RepositoryImpl$$EnhancerByGuice$$c5f0822b{type=group, format=maven2, name='maven-public'}
Repository Configuration: Configuration{repositoryName='maven-public', recipeName='maven2-group', attributes={maven={versionPolicy=MIXED}, group={memberNames=[maven-releases, maven-snapshots, maven-central]}, storage={blobStoreName=default}}}

which is pretty good result, at least you can capture in one go all the configuration of all your repositories.



This task will delete all your repos:

import org.sonatype.nexus.repository.Repository

repository.repositoryManager.browse().each { Repository repo ->
    log.info("DELETE Repository: $repo")
    repository.repositoryManager.delete("$repo.name")
}
