unknown packaging nar - nar-maven-plugin
I use Maven to manage my Java projects build but sometimes I have projects written in C or C++ langage and I would like to use Maven too so it will be easier to manage those projects.
It seems the nar-maven-plugin should do the job. I tried to create an HelloWorld project just to test it. I thought it will be really simple as it is generally with Maven.
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.sample</groupId> <artifactId>helloworld-cplusplus-sample</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>nar</packaging> <name>Helloworld</name> <build> <plugins> <plugin> <groupId>com.github.maven-nar</groupId> <artifactId>nar-maven-plugin</artifactId> <version>3.2.3</version> <configuration> <libraries> <library> <type>executable</type> </library> </libraries> </configuration> </plugin> </plugins> </build> </project>
And i have the following error
[INFO] Scanning for projects... [ERROR] [ERROR] Some problems were encountered while processing the POMs: [ERROR] Unknown packaging: nar @ line 7, column 14 @ [ERROR] The build could not read 1 project -> [Help 1] [ERROR] [ERROR] The project com.sample:helloworld-cplusplus-sample:0.0.1-SNAPSHOT (D:\local\workspaces\TEST\HelloWorl dMaven\pom.xml) has 1 error [ERROR] Unknown packaging: nar @ line 7, column 14 [ERROR] [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.

I'm using Maven 3.3.1.
I forced the download of nar-maven-plugin in my local repository using "mvn dependency:get ..." but it doesn't change anything.
As already answered, ;)
link.exe is part of Microsoft Visual Studio, which is what NAR typically uses under the hood to compile C++ code on Windows.
<linker> <name>g++</name> </linker>
in your nar plugin configuration if you have MinGW or something other than MSVS.
When a plugin adds a new packaging type, you must add <extensions>true</extensions> to its definition:
<plugin> <groupId>com.github.maven-nar</groupId> <artifactId>nar-maven-plugin</artifactId> <version>3.2.3</version> <extensions>true</extensions> <!-- This needs to be present for a new packaging --> <configuration> <libraries> <library> <type>executable</type> </library> </libraries> </configuration> </plugin>
