Unresolved import with npm React portlet with Liferay ce 7.0

Question

So, my goal is to learn to create Liferay portlet using React in framework development. I have follewed instructions and used maven to build my project

mvn archetype:generate \
-DarchetypeGroupId=com.liferay \
-DarchetypeArtifactId=com.liferay.project.templates.npm.react.portlet \
-DgroupId=com.liferay \
-DartifactId=my-npm-react-portlet \
-Dpackage=com.liferay.npm.react \
-Dversion=1.0 \
-DclassName=MyNpmReactPortlet \
-DpackageJsonVersion=1.0.0

Proplem now occures when I am deploying my freshy made portlet. Server doesnt print anything else to console than processing my-npm-react-portlet-1.0.jar

I have checked my modules with Blade sh lb and blade sh diag and outcome is:

 Unresolved requirement: Import-Package: com.liferay.frontend.js.loader.modules.extender.npm; version="[1.0.0,2.0.0)"

Project bnd.bnd

Bundle-Name: my-npm-react-portlet <br/>
Bundle-SymbolicName: com.liferay.npm.react <br/>
Bundle-Version: 1.0 <br>
Export-Package: com.liferay.npm.react.constants <br/>
Web-ContextPath: /my-npm-react-portlet <br/>
-jsp: *.jsp,*.jspf <br/>
-plugin.jsp: com.liferay.ant.bnd.jsp.JspAnalyzerPlugin <br/>
-plugin.npm: com.liferay.ant.bnd.npm.NpmAnalyzerPlugin <br/>
-plugin.resourcebundle: <br/>com.liferay.ant.bnd.resource.bundle.ResourceBundleLoaderAnalyzerPlugin <br/>
-plugin.sass: com.liferay.ant.bnd.sass.SassAnalyzerPlugin <br/>
-sass: *
Bundle-Name: my-npm-react-portlet
Bundle-SymbolicName: com.liferay.npm.react
Bundle-Version: 1.0
Export-Package: com.liferay.npm.react.constants
Web-ContextPath: /my-npm-react-portlet
-jsp: *.jsp,*.jspf
-plugin.jsp: com.liferay.ant.bnd.jsp.JspAnalyzerPlugin

-plugin.resourcebundle: com.liferay.ant.bnd.resource.bundle.ResourceBundleLoaderAnalyzerPlugin
-plugin.sass: com.liferay.ant.bnd.sass.SassAnalyzerPlugin
-sass: *

And last pom.xml (code block doesn't want to work with this one).

I recently worked on a Gradle, bnd Liferay module. I ran into similar unresolved requirement issues. I am not sure if this will help you or applies to your issue.

In my case, I found that the bnd.bnd file needs the import statements to be in the exact specific format. I am guessing it applies to the export statements as well. If not in this format, there is no error but there are deployment/run time issues like yours.

The following with commas, * and \ worked for me, rather than multiple import statements. I ran into this information buried on the Liferay forums. I don't remember the exact post that helped me.

Import-Package: \
com.xyz.core.api, \
com.xyz..core.api.model, \
com.liferay.portal.kernel.*, \
*

Here is the bnd documentation in case it helps: http://bnd.bndtools.org/chapters/390-wrapping.html Hope this helps.
