Subject Fwd: unit test error for new parser
Date Tue, 03 Jun 2014 22:07:09 GMT
Hi dev group,

I've put together a new parser for Matlab (.mat) files.  I successfully
compile and execute the new parser at the command line as:

javac -classpath
../../../../tika-core/target/tika-core-1.6-SNAPSHOT.jar:../../../../jmatio-1.2.jar
 edu/usc/sunset/burgess/tika/MatParser.java

java -classpath
annie-parsers.jar:tika-app/target/tika-app-1.6-SNAPSHOT.jar:jmatio-1.2.jar
org.apache.tika.cli.TikaCLI --metadata
/Users/annbryant/POLARCYBER/breidamerkurjokull_radar_profiles_2009.mat


However, I've written a unit test for the new parser and have come to a
roadblock.

The new parser uses a 3rd party jar, JmatIO, file available on Maven
Central (
http://search.maven.org/#artifactdetails%7Cnet.sourceforge.jmatio%7Cjmatio%7C1.0%7Cjar
), which I have included as a dependency in the tika-parsers/pom.xml with
the following:

     <dependency>
      <groupId>net.sourceforge.jmatio</groupId>
      <artifactId>jmatio</artifactId>
      <version>1.0</version>
    </dependency>


When I run the unit test in maven, maven seems to be able to find the
appropriate class files from the 3rd party jar, i.e. I don't get any
"missing package" or "can't find symbol' errors from the 'import'
commands:  import com.jmatio.io.MatFileHeader;  However, the test fails
when the first instance of one of the JmatIO classes is called within the
parser.

Are there some steps I'm missing when integrating a third party jar in a
unit test?

I have attached the new parser and the parser test.

Please let me know if any other information would be useful.

Annie
