我正在使用"可定位资源插件"和Jenkins多流水线功能：
lock('my-resource-name') {
}
我遇到的情况是，我需要将资源锁定在一个管道中，然后在另一个管道中将其解锁。我有变通办法，但如果可能的话，我更喜欢使用锁插件。
我想象一下类似的东西
lock("my-resource-name")
.....
unlock("my-resource-name)
为什么
我正在实现canary版本，我的管道有三条不同的路径(我考虑了其他解决方案，比如用输入插件暂停管道——为我提供更多内容超出了这个问题的范围(。我想在评估金丝雀时锁定/停止管道，然后在升级或回滚完成后再次解锁它。省略lock语句的正文只会给我java.lang.IllegalStateException: There is no body to invoke
一种方法是：
curl -XGET https://your-jenkins/lockable-resources/reserve?resource=myresource
curl -XGET https://your-jenkins/lockable-resources/unreserve?resource=myresource
GET不是一个错误，它确实是GET。
等待锁定
lock("my-resource-name") {}
我也知道Jenkins支持一种叫做"里程碑"的东西，显然是用来在构建之间进行通信的东西。但我不知道它是否能以任何有意义的方式解决这个问题。
可以通过这种方式锁定
import org.jenkins.plugins.lockableresources.LockableResource
import org.jenkins.plugins.lockableresources.LockableResourcesManager
...
LockableResourcesManager lockableResourcesManager = LockableResourcesManager.get()
LockableResource lockableResource = lockableResourcesManager.fromName(resourceName)
// if the resource doesn't exists, create it
if (lockableResource == null) {
lockableResourcesManager.createResource(resourceName)
lockableResource = lockableResourcesManager.fromName(resourceName)
}
// wait until lock is successful
waitUntil { lockableResourcesManager.lock([lockableResource].toSet(), currentBuild.rawBuild, null) }
解锁要简单得多，因为你知道资源存在(如果不存在，就没有理由尝试解锁(
LockableResourcesManager lockableResourcesManager = LockableResourcesManager.get()
LockableResource lockableResource = lockableResourcesManager.fromName(resourceName)
// do not pass currentBuild.rawBuild as in your case is not the build that locked this resource
// so I am passing null instead
lockableResourcesManager.unlock([lockableResource], null)
请注意，我曾经测试过这个org.6wind.jenkins:lockable-resources:2.7，实现细节可能会因使用的版本而异。
<dependency>
<groupId>org.6wind.jenkins</groupId>
<artifactId>lockable-resources</artifactId>
<version>2.7</version>
<scope>provided</scope>
</dependency>
从LockableResourcesManager获取每个锁，然后foreach lock如果lock.getName匹配则执行lock.reset((以释放锁定
例如，一些groovy可以找到任何构建都不拥有的锁定锁并清理它们：
print "STARTn"
def all_lockable_resources = org.jenkins.plugins.lockableresources.LockableResourcesManager.get().resources
all_lockable_resources.each { r->
if (r.isLocked() || r.isReserved()) {
println "Lock " + r + " is locked or reserved by " + r.getBuild() + " B CARSE " + r.getLockCause()
b = r.getBuild()
if (b) {
if (b.isBuilding()) { println "build:" + b + " is building" }
if (b.getResult().equals(null)) { println "build:" + b + " result is not in yet" }
if ( ! b.isBuilding() && ! b.getResult().equals(null)) {
println "build:" + b + " is not building and result is " + b.getResult() + " yet the lock " + r + " is locked."
println "ACTION RELEASE LOCK " + r
println "getLockCause:" + r.getLockCause()
println "getDescription:" + r.getDescription()
println "getReservedBy:" + r.getReservedBy()
println "isReserved:" + r.isReserved()
println "isLocked:" + r.isLocked()
println "isQueued:" + r.isQueued()
//release the lock
r.reset()
println "getLockCause:" + r.getLockCause()
println "getDescription:" + r.getDescription()
println "getReservedBy:" + r.getReservedBy()
println "isReserved:" + r.isReserved()
println "isLocked:" + r.isLocked()
println "isQueued:" + r.isQueued()
}
}
}
}
