清理nexus3日志,从Nexus3清除旧版本

I use Nexus 3 and I want to delete my old releases. In Nexus 2 there is a scheduled task called Remove Releases From Repository. It seems that this tasks is missing in Nexus 3.

How can we delete old release from Nexus 3 ?

Thanks

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 &＃61; null;

Logger log &＃61; null;

GlobalComponentLookupHelper container &＃61; null;

// ----------------------------------------------------

def retentionDays &＃61; 30;

def retentionCount &＃61; 10;

def repositoryName &＃61; &＃39;maven-releases&＃39;;

def whitelist &＃61; ["org.javaee7.sample/javaee7-simple-sample", "org.javaee7.next/javaee7-another-sample"].toArray();

log.info(":::Cleanup script started!");

MaintenanceService service &＃61; container.lookup("org.sonatype.nexus.repository.maintenance.MaintenanceService");

def repo &＃61; repository.repositoryManager.get(repositoryName);

def tx &＃61; repo.facet(StorageFacet.class).txSupplier().get();

def components &＃61; null;

try {

tx.begin();

components &＃61; tx.browseComponents(tx.findBucket(repo));

}catch(Exception e){

log.info("Error: "&＃43;e);

}finally{

if(tx!&＃61;null)

tx.close();

}

if(components !&＃61; null) {

def retentionDate &＃61; DateTime.now().minusDays(retentionDays).dayOfMonth().roundFloorCopy();

int deletedComponentCount &＃61; 0;

int compCount &＃61; 0;

def listOfComponents &＃61; ImmutableList.copyOf(components);

def previousComp &＃61; listOfComponents.head().group() &＃43; listOfComponents.head().name();

listOfComponents.reverseEach{comp ->

log.info("Processing Component - group: ${comp.group()}, ${comp.name()}, version: ${comp.version()}");

if(!whitelist.contains(comp.group()&＃43;"/"&＃43;comp.name())){

log.info("previous: ${previousComp}");

if(previousComp.equals(comp.group() &＃43; comp.name())) {

compCount&＃43;&＃43;;

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&＃43;&＃43;;

}

}

} else {

compCount &＃61; 1;

previousComp &＃61; comp.group() &＃43; comp.name();

}

}else{

log.info("Component skipped: ${comp.group()} ${comp.name()}");

}

}

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

}
