Cypress Build error during mvn clean install for AEM as a Cloud service

[RekhaRa4]

I am trying to build my aem project for a local setup but keep getting this error:

"Failed to execute goal com.github.eirslett:frontend-maven-plugin:1.12.0:npm (npm ci) on project com.adobe.cq.cloud.testing.ui.cypress.tests: Failed to run task: 'npm ci' failed. org.apache.commons.exec.ExecuteException: Process exited with an error: 1 (Exit value: 1)"

Tried downloading the specific version required for cypress, tried deleting the node-modules folder as well but unable to remove this error. Kindly refer the below screenshots for more information on the exact error:

I am currently using the AEM cloud version, archetype 51 was used to build the project, npm version is 10.9.2 and node version v22.13.1. Kindly provide suggestions on what can be done to remove this error as I have tried with WKND as well as standalone project too.

Hi @RekhaRa4 ,

I think the error you are getting is because your project uses AEM Archetype 51, which includes Cypress tests and a frontend build pipeline. These expect Node.js 18 and npm 8.
You're currently using:

• Node.js 22.13.1
• npm 10.9.2

These versions are too new and unsupported by several dependencies (especially Cypress & older frontend tooling).

1. Downgrade to Node 18 and npm 8

Use Node Version Manager (nvm):

• nvm install 18
• nvm use 18

2. Clean the Frontend Workspace:- In the ui.frontend or ui.tests folder (where Cypress lives):

• rm -rf node_modules package-lock.json
• npm cache clean --force

3. Re-run Maven Build

• From project root: mvn clean install
• Or with deployment: mvn clean install -PautoInstallSinglePackage

Try this and let me if it works.

thanks.

Hi @RekhaRa4 ,

During mvn clean install, the Cypress tests fail to build due to a corrupted Cypress binary download.

The root cause is incompatible Node/npm versions and possibly a network/proxy issue.

You're using:

Node.js: v22.13.1

npm: 10.9.2

AEM Archetype: 51 (which expects older tooling)

Cypress and the AEM Archetype 51 frontend plugin are not compatible with Node 22 or npm 10.

Try below solution:

1. Switch to Correct Node & npm Versions

Use nvm to manage Node versions:

nvm install 18
nvm use 18

This will give you Node 18 and npm ~8, which are fully compatible with Cypress 13.14.1 and AEM archetype 51.

2. Clean Frontend Environment

Inside the Cypress test module (likely ui.tests or com.adobe.cq.cloud.testing.ui.cypress.tests):

rm -rf node_modules package-lock.json
npm cache clean --force

This ensures no residual corrupt/cached content interferes.

3. Manually Trigger Cypress Binary Download (Optional but Safe)

Sometimes the Cypress binary fails via npm ci due to checksum mismatch or network restrictions. You can pre-install it:

npm install cypress@13.14.1
npx cypress verify

This downloads the binary cleanly and verifies its integrity.

4. Build Again Using Maven

From the project root:

mvn clean install

If you also want to deploy to your local AEM SDK:

mvn clean install -PautoInstallSinglePackage

Regards,
Amit
