推荐答案

自从nexus 3发行以来，您可以将groovy脚本部署到nexus管理器中.只需创建一个新的执行脚本任务并使用以下脚本:

Since the release of nexus 3 you can deploy groovy scripts to the nexus manager. Simply create a new execute script task and use the following script:

import org.sonatype.nexus.repository.storage.StorageFacet;
import org.sonatype.nexus.common.app.GlobalComponentLookupHelper
import org.sonatype.nexus.repository.maintenance.MaintenanceService
import org.sonatype.nexus.repository.storage.ComponentMaintenance
import org.sonatype.nexus.repository.storage.Query;
import org.sonatype.nexus.script.plugin.RepositoryApi
import org.sonatype.nexus.script.plugin.internal.provisioning.RepositoryApiImpl
import com.google.common.collect.ImmutableList
import org.joda.time.DateTime;
import org.slf4j.Logger

// ----------------------------------------------------
// delete these rows when this script is added to nexus
RepositoryApiImpl repository = null;
Logger log = null;
GlobalComponentLookupHelper container = null;
// ----------------------------------------------------

def retentionDays = 30;
def retentionCount = 10;
def repositoryName = 'maven-releases';
def whitelist = ["org.javaee7.sample/javaee7-simple-sample", "org.javaee7.next/javaee7-another-sample"].toArray();


log.info(":::Cleanup script started!");
MaintenanceService service = container.lookup("org.sonatype.nexus.repository.maintenance.MaintenanceService");
def repo = repository.repositoryManager.get(repositoryName);
def tx = repo.facet(StorageFacet.class).txSupplier().get();
def components = null;
try {
    tx.begin();
    components = tx.browseComponents(tx.findBucket(repo));
}catch(Exception e){
    log.info("Error: "+e);
}finally{
    if(tx!=null)
        tx.close();
}

if(components != null) {
    def retentionDate = DateTime.now().minusDays(retentionDays).dayOfMonth().roundFloorCopy();
    int deletedComponentCount = 0;
    int compCount = 0;
    def listOfComponents = ImmutableList.copyOf(components);
    def previousComp = listOfComponents.head().group() + listOfComponents.head().name();
    listOfComponents.reverseEach{comp ->
        log.info("Processing Component - group: ${comp.group()}, ${comp.name()}, version: ${comp.version()}");
        if(!whitelist.contains(comp.group()+"/"+comp.name())){
            log.info("previous: ${previousComp}");
            if(previousComp.equals(comp.group() + comp.name())) {
                compCount++;
                log.info("ComCount: ${compCount}, ReteCount: ${retentionCount}");
                if (compCount > retentionCount) {
                    log.info("CompDate: ${comp.lastUpdated()} RetDate: ${retentionDate}");
                    if(comp.lastUpdated().isBefore(retentionDate)) {
                        log.info("compDate after retentionDate: ${comp.lastUpdated()} isAfter ${retentionDate}");
                        log.info("deleting ${comp.group()}, ${comp.name()}, version: ${comp.version()}");

                        // ------------------------------------------------
                        // uncomment to delete components and their assets
                        // service.deleteComponent(repo, comp);
                        // ------------------------------------------------

                        log.info("component deleted");
                        deletedComponentCount++;
                    }
                }
            } else {
                compCount = 1;
                previousComp = comp.group() + comp.name();
            }
        }else{
            log.info("Component skipped: ${comp.group()} ${comp.name()}");
        }
    }

    log.info("Deleted Component count: ${deletedComponentCount}");
}
