Hi,
first rule in Maven keep the conventions[1]...meaning convention over
configuration:
source code:
src/main/java
resources for production code:
src/main/resources
Tests:
src/test/java
resources for tests:
src/test/resources
move your files to the correct location
etc.
Remove the following lines:
<sourceDirectory>${basedir}/src/org/apache/hadoop/mapred/examples</sourceDirectory>
maven-compiler-plugin:
> <includes>
> <include>src/**/*.java</include>
> </includes>
does not make sense at all:
> <resources>
> <resource>
> <directory>target</directory>
> <includes><include>**/*.class</include></includes>
> </resource>
> <resource>
> <directory>src/main/resources/META-INF</directory>
> <targetPath>${basedir}/target</targetPath>
> <includes> <include>log4j.properties</include>
> <include>servers.json</include> </includes>
> </resource>
> </resources>
Kind regards
