Usage

Usage of ./jitic:
  -issues string
        Message to retrieve the issues from.
  -pass string
        JIRA Password.
  -stdin
        If set to true you can stream "-issues" to stdin instead of an argument. If set "-issues" will be ignored.
  -url string
        JIRA instance URL (format: scheme://[username[:password]@]host[:port]/).
  -user string
        JIRA Username.
  -verbose
        If activated more information will be written to stdout .
  -version
        Outputs the version number and exits.

Examples

Check if issue MESOS-3136 exists in https://issues.apache.org/jira/ from parameter:

$ ./jitic -url="https://issues.apache.org/jira/" -issues="MESOS-3136 - Fix command health check"; echo "Exit code: $?"
Exit code: 0

Check if issue MESOS-3136 exists in https://issues.apache.org/jira/ from stdin.

$ echo "MESOS-3136 - Fix command health check" | ./jitic -url="https://issues.apache.org/jira/" -stdin; echo "Exit code: $?"
Exit code: 0

Check if a fake issue MESOS-123456 exists in https://issues.apache.org/jira/ from parameter:

$ ./jitic -url="https://issues.apache.org/jira/" -issues="MESOS-123456 - Not existing issue" -verbose; echo "Exit code: $?"
2017/11/28 15:41:26 JIRA Request for issue MESOS-123456 returned 404 Not Found (404)

Use cases

Subversion "pre-commit" hook

See Implementing Repository Hooks and pre-commit.

How a pre-commit hook can look like:

#!/bin/sh

REPOS="$1"
TXN="$2"

# Get the commit message
SVNLOOK=/usr/bin/svnlook
COMMIT_MSG=$($SVNLOOK log -t "$TXN" "$REPOS")

JITIC=/usr/bin/jitic
JIRA_URL="https://jira.example.org/"
JIRA_USERNAME="JIRA-API"
JIRA_PASSWORD="SECRET-PASSWORD"

# Exit on all errors.
set -e

# Auth against JIRA and check if the issue(s) exists
$JITIC -url="$JIRA_URL" -user="$JIRA_USERNAME" -pass="$JIRA_PASSWORD" -issues="$COMMIT_MSG"

# All checks passed, so allow the commit.
exit 0

Pro-Tip: Set the variables JIRA_USERNAME and JIRA_PASSWORD in a seperate file and import this file via source into the hook. With this you can store the pre-commit hook itself in git + deploy it with configuration management.

Git "pre-receive" hook

See Customizing Git - Git Hooks and A reasonable git pre-receive-hook and Can git pre-receive hooks evaulate the incoming commit?.

How a pre-receive hook can look like:

#!/bin/sh

GIT=/usr/local/bin/git
JITIC=/usr/bin/jitic
JIRA_URL="https://jira.example.org/"
JIRA_USERNAME="JIRA-API"
JIRA_PASSWORD="SECRET-PASSWORD"
