During portlet WAR deployment getting unresolved requirement errors

Issue

When deploying a spring portlet WAR using JDK 17 or JDK 21, the following deployment error appears in the Liferay logs:

Unresolved requirement: Import-Package: com.liferay.portal.osgi.web.servlet.jsp.compiler; resolution:="optional"_ Unresolved requirement: Import-Package: com.liferay.portal.spring.context; resolution:="optional"_ Unresolved requirement: Require-Capability:osgi.ee; filter:="(osgi.ee=UNKNOWN)"_ [Sanitized]

Environment

2024.Q1

Resolution

Liferay DXP uses an OSGi-based framework that requires modules to specify their Java Execution Environment (osgi.ee). However, WAR-based portlets lack this declaration.
During deployment, Liferay tries to wrap the WAR as an OSGi bundle but fails due to the missing osgi.ee version, assigning it "UNKNOWN", which leads to deployment errors.
To prevent this error, disable OSGi execution environment validation by adding the following line to the liferay-plugin-package.properties or bnd.bnd file:
```
-noee: true
```
Once the module is redeployed, the deployment should succeed without OSGi validation errors.
