I.e. this project will not have any sourcefiles, only the 4 DLLs.
We faced the same problem. Originally we tried to publish the DLL artifact into the repository directly, but this caused problems for us, as our JNI native code had to run on Windows, Linux and Solaris, and maintaining the proper naming conventions and suffixes was a pain. We eventually opted to wrap the JNI DLLs / .so files inside a jar, and publish the jar in the repository, including a classifier to show both the platform (windows / linux / solaris) and architecture (x86, amd64, etc). >From that point on we only needed to worry about the name of the jar, which was consistent across platforms. When you have multiple DLLs, putting them in a jar reduces them down from many artifacts to one artifact, which is easier to deal with. This is the pom we use, it should give some clues. The DLLs are built by ant using the antrun plugin, and maven worries about the packaging and deployment: <project xmlns="http://maven.apache.org/POM/4.0.0"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd";> <modelVersion>4.0.0</modelVersion> <parent> <artifactId>alchemy-ii-native</artifactId> <groupId>alchemy</groupId> <version>4.0.30-SNAPSHOT</version> </parent> <artifactId>alchemy-cdo</artifactId> <packaging>jar</packaging> <name>Alchemy Native CDO</name> <description>Placeholder for the CDO stuff from London</description> <build> <extensions> <extension> <groupId>org.apache.maven.wagon</groupId> <artifactId>wagon-webdav</artifactId> <version>1.0-beta-2</version> </extension> </extensions> <sourceDirectory>src/main/java</sourceDirectory> <!-- <testSourceDirectory>src</testSourceDirectory>--> <resources> <resource> <directory>target/build</directory> <includes> <include>*.dll</include> </includes> </resource> <resource> <directory>target/build</directory> <includes> <include>*.dylib</include> </includes> </resource> <resource> <directory>target/build</directory> <includes> <include>*.so</include> </includes> </resource> <resource> <directory>src/main/resources</directory> <filtering>true</filtering> <includes> <include>alchemy-cdo-version.properties</include> </includes> </resource> </resources> <plugins> <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>native-maven-plugin</artifactId> <extensions>true</extensions> <!-- Generate JNI header files based on a list of class name on the classpath --> <!-- The generated include directory is automatically added to include path at compile phase --> <!-- Ensure to have appropriate denpendency jar file(s) in your pom --> <executions> <execution> <id>javah</id> <phase>generate-sources</phase> <configuration> <classNames> <className>alchemy.cdo.measure.CDOTranche</className> </classNames> <!-- | Note: | 1.
