We use frontend-maven-plugin in a pretty straightforward matter. Recently we bumped the version of the plugin from 1.12.0 to 1.12.1 and the project started failing with the following error

[ERROR] Failed to execute goal com.github.eirslett:frontend-maven-plugin:1.12.1:install-node-and-npm (install node and npm) on project bosun-api-parent: Execution install node and npm of goal com.github.eirslett:frontend-maven-plugin:1.12.1:install-node-and-npm failed: A required class was missing while executing com.github.eirslett:frontend-maven-plugin:1.12.1:install-node-and-npm: org/apache/http/protocol/HttpContext

I noticed that in 1.12.1, the version of httpclient was updated to the latest (4.5.13) from 4.5.2. The pom file of the plugin also doesn't include httpcore which contains the HttpContext interface which appears to be referenced. Is it possible the Apache Http Client/Core to have refactored/moved stuff where httpcore is now required also to be included thus now the execution of the plugin fails?

I also have the following extended output

[WARNING] The POM for org.apache.httpcomponents:httpclient:jar:4.5.13 is invalid, transitive dependencies (if any) will not be available: 3 problems were encountered while building the effective model for org.apache.httpcomponents:httpclient:4.5.13

Anyways, any help/workaround is appreciated...

Additionally, if i pull "master" from this project and "mvn clean package", it fails to compile with

But if i add

        <dependency>
            <groupId>org.apache.httpcomponents</groupId>
            <artifactId>httpcore</artifactId>
            <version>4.4.15</version>
        </dependency>

to "frontend-maven-plugin/frontend-plugin-core/pom.xml" it builds cleanly. I am not sure if the issue is on my end because obviously the project was built and released without httpcore...

[gstanchev]

Okay, so after building and installing 1.12.2-SNAPSHOT locally with added httpcore dependency, and pointing our project to use that, tests are no longer failing so I can confirm it fixes the issue for us
