Publishing a snapshot JAR to Artifactory Maven repository fails to deploy

My team is trying to deploy a JAR generated by a Jenkins job to a repository in our Artifactory Pro 7.6.2 instance that is set up as a Maven snapshot repo. However, when performing the actual upload of the generated JAR file from the project the deploy fails with an error 500.

This is what is in the console output of the Jenkins job:

On the Artifactory server side, the following is shown in log when this fails (this is repeated for each file that failed, just putting one example here):

The Jenkins job is a declarative multibranch pipeline and the Artifactory deployment is done via the following code within the Jenkinsfile:

...
dir("mavenOut/snapshot/"){
rtBuildInfo(maxBuilds: 10)
rtUpload(
serverId: "artifactory", 
spec: """{
"files":[
{
"pattern": "**/*",
"excludePatterns": ["*maven-metadata.xml", "*.sha1","*.sha256","*.sha512","*.md5"],
"target":  "maven-dev/",
"flat": "false"
}
]
}"""
)
rtPublishBuildInfo(serverId: "artifactory")
}
...

The project itself is a Java project built with Gradle:

plugins {
id 'java-library'
id 'maven-publish'
id 'maven'
}
group = 'com.example'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '1.8'
repositories {
mavenCentral()
}
dependencies {
implementation 'javax.websocket:javax.websocket-api:1.0'
implementation 'org.springframework:spring-websocket:5.2.7.RELEASE'
implementation 'org.springframework:spring-messaging:5.2.7.RELEASE'
implementation 'com.fasterxml.jackson.core:jackson-databind:2.11.2'
implementation 'com.google.code.gson:gson:2.8.6'
implementation 'org.apache.tomcat.embed:tomcat-embed-websocket:9.0.37'
testCompile('org.springframework.boot:spring-boot-starter-test:2.3.0.RELEASE') {
exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
}
}
java {
withJavadocJar()
withSourcesJar()
}
publishing {
publications {
mavenJava(MavenPublication) {
artifactId = 'example-client'
from components.java
}
}
repositories {
maven {
def releasesRepoUrl = "$buildDir/mavenOut/release"
def snapshotsRepoUrl = "$buildDir/mavenOut/snapshot"
url = version.endsWith('SNAPSHOT') ? snapshotsRepoUrl : releasesRepoUrl
}
}
}
test {
useJUnitPlatform()
}

Ultimately, we end up with 5 files that need to get deployed (the timestamps change on each build of course):

• example-client-0.0.1-20200817.130343-1.jar
• example-client-0.0.1-20200817.130343-1-javadoc.jar
• example-client-0.0.1-20200817.130343-1-sources.jar
• example-client-0.0.1-20200817.130343-1.module
• example-client-0.0.1-20200817.130343-1.pom

The Maven repository (maven-dev) within Artifactory is set up with the following settings:

• Checksum policy: Verify against client checksums
• Maven Snapshot Version Behavior: Unique
• Max Unique Snapshots: <empty>
• Handle Releases: unchecked
• Handle Snapshots: checked
• Suppress POM Consistency Checks: checked

I'm hoping that someone else has deployed a project like this to an Artifactory repo to point out what's going wrong. We've used Artifactory extensively for a number of years but not in the context of deploying snapshot builds to a Maven repository.

EDIT: I have narrowed down the issue to the fact that we're trying to upload the *-sources.jar in addition to the main jar and the *-javadoc.jar. If I update the exclude filter in the file spec to the following then the publish works flawlessly as expected:

"excludePatterns": ["*maven-metadata.xml","*.sha1","*.sha256","*.sha512","*.md5","*sources.jar"],

So something about the sources.jar getting published is throwing it off, any ideas?

EDIT 2: Well, excluding the sources jar worked for several builds then it started failing again with the same error. It will work for a build or two then fail for a while, then back to a few successes it seems.

EDIT 3: I also tried deploying via the Artifactory Gradle syntax rather than the more generic rtUpload approach. The Gradle build runs and the buildinfo publishes but no artifacts are uploaded.

** EDIT 4:**
I got it working based on suggestions below. I also updated the Artifactory Jenkins plugin to the latest. Here's the snippet from the Jenkinsfile that ended up working just in case someone else runs into a similar issue.

   stage('Artifactory Config') {
steps {
rtBuildInfo(maxBuilds: 10, deleteBuildArtifacts: true)
rtGradleDeployer(
id: "rtDeployer",
serverId: "artifactory",
releaseRepo: "gradle-release",
snapshotRepo: "gradle-dev"
)
rtGradleResolver(
id: "rtResolver",
serverId: "artifactory",
repo: "maven"
)
}
}
stage('Build Client'){
steps {
echo "invoking gradle"
rtGradleRun(
tasks: "artifactoryPublish",
useWrapper: true,
deployerId: "rtDeployer",
resolverId: "rtResolver"
)
rtPublishBuildInfo(serverId: "artifactory")
}
}

I would suggest building and deploying Gradle artifacts using the dedicated Gradle integration offered in the Jenkins Artifactory Plugin.

This might prevent issues like those you are facing now since it is developed specifically for Gradle builds, unlike the generic command (rtUpload) you are currently using.

See this Jenkinsfile example to learn how to easily use this integration in your pipeline.

Based on error log snippet, I could see that the error is related to the deadlock in the DB transactions. I think Artifactory is running with the default derby DB.
The below error log snippet tells that there was deadlock situation in Derby,

> Caused by: org.apache.derby.iapi.error.StandardException: A lock could not be obtained due to a deadlock, cycle of locks and waiters is:
Lock : ROW, NODES, (2975,6)
Waiting XID : {230127895, S} , APP, SELECT * FROM nodes WHERE repo = ? AND node_path = ? AND depth = ?
Granted XID : {230127897, X}
Lock : ROW, NODES, (991,272)
Waiting XID : {230127897, S} , APP, SELECT * FROM nodes WHERE repo = ? AND node_path = ? AND depth = ?
Granted XID : {230127895, X}

I had a similar JenkinFile which deploys Artifacts to Artifactory and never faced this issue. I believe a simple restart of Artifactory should be enough to remove the Derby DB from the deadlock state.
