I am developing application that uses Cassandra NoSQL database and I am adding web interface. I have 2 projects: cassandra-access (this project is DAL) and web (this project is web application).
Scenario is simple enaugh. Cassandra-access has dependencies on hector.jar which is not in maven repository. So I added this dependency to my local repository via mvn install:install-file and I list my repository in parent pom:
<repositories>
<repository>
<id>loc</id>
<url>file://${basedir}/../mvn-local-repository</url>
</repository>
</repositories>
In Web projects pom I added dependency on Cassandra-access. But when i start the Web application with hello world read from database I am getting classNotFound exception as if the hector.jar isn't on class path. When I write mvn clean install the resulting war of web project doesn't include hector.jar in WEB-INF/lib. That further confirms my theory.
How to achieve that war get's all the transitive dependcies? I thought that all dependencies that are in scope compile (which is default) will get copied.
Web projects pom:
<dependency>
<groupId>net.product</groupId>
<artifactId>cassandra-access</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
Cassandra-access pom:
<dependency>
<groupId>me.prettyprint</groupId>
<artifactId>hector</artifactId>
<version>0.7.0</version>
</dependency>
It maybe not the optimal solution but it works for me: put the hector jar in the lib directory of the cassandra access. add to the cassandra-access pom:
<dependency>
<groupId>%HECTOR_JAR_GROUP_ID%</groupId>
<artifactId>%HECTOR_JAR_ARTIFACT_ID%</artifactId>
<version>%HECTOR_JAR_VERSION%</version>
<scope>system</scope>
<systemPath>${basedir}/lib/%HECTOR_JAR_NAME%</systemPath>
</dependency>
then add the following plugin:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>copy-dependencies</id>
<phase>package</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<outputDirectory>${project.build.directory}/lib</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
