GitLab + Jenkins CI/CD for Nexacro (Part 3)

Jenkins has plugins like ssh-agent and Publish Over SSH, but I preferred not to depend on them, so I built the flow without those plugins.

This project uses Nexacro on the frontend. The pipeline is:

• Nexacro build
• Maven build
• Deploy via scp

Jenkins server SSH key

To use scp over SSH, generate an SSH key and register it on the deploy target.

ssh-keygen

Press Enter with no passphrase. Put the generated .ssh\id_rsa.pub into the remote server (dev) at /root/.ssh/authorized_keys:

scp -r .ssh\id_rsa.pub root@HOST_IP:/root/.ssh/authorized_keys
chmod 700 /root/.ssh
chmod 600 /root/.ssh/authorized_keys

If you skip the permission settings after copying, scp from Jenkins to the deploy server will prompt for a password and the job will hang.

This job uses a freestyle project instead of a Pipeline job. GitLab connection settings follow the earlier post (GitLab & Jenkins basic setup and webhook integration).

JDK uses 1.8 — install and register it the same way as 1.6.

When configuring Git, you should not see red error text (that means the connection failed).

Build triggers are set the same way as in the GitLab & Jenkins webhook post.

Build steps

Nexacro build

Because Jenkins runs on a Windows server, every step except the Maven build uses Execute Windows batch command.

Move into the Nexacro install directory and build. The Nexacro manual shows a command like:

nexacrodeploy17.exe -P "xprj file in the project" -O "generate output path" -B "lib path in the project" -D "deploy output path" -MERGE

With my paths:

cd C:\Program Files (x86)\nexacro\17.1
nexacrodeploy17.exe -P "C:\ProgramData\Jenkins\.jenkins\workspace\TEST\src\main\sgnx_ui_17_1\sgnx_ui.xprj" -O "C:\ProgramData\Jenkins\.jenkins\workspace\TEST\src\main\webapp\ui" -B "C:\ProgramData\Jenkins\.jenkins\workspace\TEST\sgnx_generate\nexacro17lib" -D "D:\jenkins\deploy_glb\ui" -MERGE

Maven build

Choose Invoke top-level Maven targets:

• clean — remove previous artifacts
• install — install artifacts to the local repository



• -P local — use the local profile

Deploy

Line breaks below are for readability only. Enter each command as a single line when you use it.

1. Stop the service and clear the previous WAR

ssh wfly@192.168.0.222 "/home/wfly/wildfly-14.0.1.Final/bin/kill.sh; rm -rd home/wfly/wildfly-14.0.1.Final/projet/deployments/ROOT.war; touch /home/wfly/wildfly-14.0.1.Final/project/deployments/ROOT.war.deployed"

2. Deploy Maven and Nexacro build outputs

scp -r C:\ProgramData\Jenkins\.jenkins\workspace\project\target\ROOT wfly14@192.168.0.222:/home/wfly/wildfly-14.0.1.Final/project/deployments/ROOT.war
scp -r D:\jenkins\deploy_glb\ui wfly14@192.168.0.222:/home/wfly/wildfly-14.0.1.Final/project/deployments/ROOT.war/

3. Start the service

ssh wfly14@192.168.0.222 "/home/wfly/wildfly-14.0.1.Final/bin/start.sh"
