Stash backup client failed with Java exception.

[Ernest Gulik]

Hello,

We're using Stash v3.0.1 on Amazon m3.medium instance type and I've setup simple backup cronjob using stash backup client but it failed and now when issue that manually it fails too.
Cronjob is simple:

30 00 * * * cd /path/to/backup && ./stash-backup

stash-backup script:

#!/bin/bash
#
# Daily backup of Stash Server.
#



DATE=$(date +%Y-%m-%d-%H_%M)
STASH_PASS="<password>"
STASH_USER="<stash-user>"
URL="http://<stash-link>"
STASH_ROOT="<stash/path>"
STASH_HOME="${STASH_ROOT}/data"
BACKUP_DIR="${STASH_ROOT}/backup/backups"
LOG_DIR="${STASH_ROOT}/backup/log"
#BACKUP_LOG="${LOG_DIR}/atlassian-sbc-" # to do
RECIPIENT="<user1>"
RETVAL=$?

MESSAGE() {
    echo "Check log file under  ${LOG_DIR}" |  /bin/mail -s "AHA Stash Backup FAILED with return code $RETVAL" ${RECIPIENT}
}

PROCESS() {
/usr/bin/java -Dstash.password="${PASS}" -Dstash.user="${STASH_USER}" -Dstash.baseUrl="${URL}" -Dstash.home="${STASH_HOME}" -jar <path/to>/stash-backup-client-1.2.1/stash-backup-client.jar stash-${DATE}.tar
}

PROCESS
#${RETVAL}
if [ ${RETVAL} -ne "0" ]; then
    MESSAGE
fi

When i execute it from command line here's what I get:

Any help appreciated,

Thank you

The reason why i was having that issue was because I extracted the package and copied over only 2 files stash backup restore and backup jar files and I learned later that these files are using libraries that are included in tar file.

Thanks

Hello,

It seems the issue is related to a version mismatch of Groovy. More specifically, it seemed it is running a compiled groovy class under A.B.C where it was compiled under X.Y.Z

Changing the library included on the classpath to X.Y.Z might resolve the issue.

I will run some tests and let you know.

Kind regards,
Rafael

Hey Rafael,

Thanks for looking into that but I was wonder how that would change since there were no updates and that backup was working at the very beggining.

Is there a package that would change the version or something like that? We haven't compiled anything, just downloaded packages and started using it as that what it states to do on documentation page if we go with stash-backup-client?

Thanks,

E.
