Get last build status
curl -s "$JENKINS_URL/job/{job-name}/lastBuild/api/json" \
  --user "$JENKINS_USER:$JENKINS_TOKEN" | jq '{result,duration,timestamp,builtOn}'
Get console output of last build
curl -s "$JENKINS_URL/job/{job-name}/lastBuild/consoleText" \
  --user "$JENKINS_USER:$JENKINS_TOKEN" | tail -50
Trigger a build
curl -s -X POST "$JENKINS_URL/job/{job-name}/build" \
  --user "$JENKINS_USER:$JENKINS_TOKEN"
Trigger with parameters
curl -s -X POST "$JENKINS_URL/job/{job-name}/buildWithParameters?BRANCH=develop&ENV=staging" \
  --user "$JENKINS_USER:$JENKINS_TOKEN"
Get build queue
curl -s "$JENKINS_URL/queue/api/json" \
  --user "$JENKINS_USER:$JENKINS_TOKEN" | jq '.items[] | {task: .task.name, why}'

Failure Analysis

When a build fails:

1. Get build result and duration:

curl -s "$JENKINS_URL/job/{job}/lastBuild/api/json" \
  --user "$JENKINS_USER:$JENKINS_TOKEN" | jq '{result,duration,timestamp}'

2. Get failed test report:

curl -s "$JENKINS_URL/job/{job}/lastBuild/testReport/api/json" \
  --user "$JENKINS_USER:$JENKINS_TOKEN" | jq '{failCount,passCount,skipCount,suites[].cases[] | select(.status=="FAILED") | {name,errorDetails}}'

3. Get console log (last 200 lines):

curl -s "$JENKINS_URL/job/{job}/lastBuild/consoleText" \
  --user "$JENKINS_USER:$JENKINS_TOKEN" | tail -200 | grep -i -E "error|fail|exception" 

4. Summarize findings in this format:

🔴 Build #{number} FAILED
⏱️ Duration: Xm Ys
📋 Tests: X passed, Y failed, Z skipped
❌ Failed tests:
  - TestClass.testMethod: error message
  - TestClass.testMethod2: error message
