opss, false alarm :( it compiles but into class version 49 (which is
incompatible with jre1.4)
i have modified pom.xml accroding to your recommendations as follows:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.5</source>
<target>1.5</target>
</configuration>
<executions>
<execution>
<id>default</id>
<phase>compile</phase>
<configuration>
<source>1.4</source>
<target>1.4</target>
</configuration>
</execution>
</executions>
</plugin>
but it seems that the classes are compiled with 1.5, not caring about the
execution definition. why on the earth that execution is ignored?? any help
will be greatly appreciated
cheers
