Exiting: ZAP requires a minimum of Java 11 to run, found looks pretty clear to me.
Whats the error when you use Java 17?
This does not look like a ZAP bug at this stage.

From logs, it clearly has "openjdk 11.0.26 2025-01-21", but not sure why it again reports "ZAP requires a minimum of Java 11 to run, found".

How have you installed ZAP? Using exactly which release and where did you get it from?

Everything was working fine until 2.15.0 version. This issue started only from latest 2.16.0 version.

The agent is installing Ubuntu 22.04.5 [Not sure if this is installing Java 11].

We have following steps in our pipeline yaml :

• sudo snap install zaproxy --classic
• sudo apt install python3-testresources
• pip install wheel
• pip install --upgrade zapcli
• Docker compose Pull and Up commands
• bash script:
  ** java --version
  sudo zaproxy -daemon -host localhost -port 8080 -silent -config api.disablekey=true -newsession $env:SYSTEM_ARTIFACTSDIRECTORY\Zap -config globalexcludeurl.url_list.url.regex='^((?!http://localhost:811).*)$' &**

If it's complaining about Java 11 you're still on 2.15 because 2.16 requires Java 17.

From logs, I see the following as part of the step 'sudo snap install zaproxy --classic':

/usr/bin/pwsh -NoLogo -NoProfile -NonInteractive -Command . '/home/vsts/work/_temp/4be285ad-3f04-4b64-a10f-eb3743724a59.ps1'
zaproxy 2.16.0 from Simon Bennetts (psiinon) installed

I think, I understood the reason. Ubuntu 22.04.5 LTS includes OpenJDK 11 as the default Java Development Kit (JDK). I will add script to install 17 version of OpenJDK and see if it makes any difference in the result.

The error is currently misleading, the newer ZAP version does require Java 17.

Anyone has an idea on how to install specific version of ZAProxy using snap install command?

Tried this, but does not work as expected -> sudo snap install zaproxy --channel=2.15/stable --classic

Older versions are not available right now, we need to manually tweak that.

I am facing the same issue but the problem is not the Java version but the zaproxy binary itself. For some reason, it is unable to get the Java version.

If I run /snap/zaproxy/40/zap.sh directly it launches just fine.

My ZAP version is 2.16.0 and my OS is Ubuntu 22.04.5 LTS.

I just tried again and the snap package is launching/running fine. I don't even have Java installed on the system, it's using the one from the snap package.
