Hi Martynas,
we have meanwhile updated the 1.3.0 version on Maven to use Java 1.6.
Could you retry and confirm if it works? We can then start snapshot
releases towards 1.3.1.
Thanks,
Holger

Hey list,
I updated my project to include the long anticipated SPIN 1.3.0 API as
a Maven dependency. It compiles fine, but when I try to run it, I get:
java.lang.Error: Unresolved compilation problem:
The method create(Function) of type SPINFunctionDrivers must
override a superclass method
at
org.topbraid.spin.arq.SPINFunctionDrivers.create(SPINFunctionDrivers.java:47)
at
org.topbraid.spin.system.SPINModuleRegistry.registerARQFunction(SPINModuleRegistry.java:250)
at
org.topbraid.spin.system.SPINModuleRegistry.register(SPINModuleRegistry.java:204)
....
Never seen this before, but from StackOverflow I get the impression
that this is related to Java versions:
http://stackoverflow.com/questions/1678122/must-override-a-superclass-method-errors-after-importing-a-project-into-eclips
Seems that in Java 1.6 @Override is allowed on both interfaces and
superclasses, while 1.5 only allows it on superclasses.
SPINFunctionDrivers seems to override interface method:
public interface SPINFunctionDriver {
SPINFunctionFactory create(Function function);
}
public class SPINFunctionDrivers implements SPINFunctionDriver {
...
@Override
public SPINFunctionFactory create(Function function) {
...
However spin-1.3.0.pom seems to specify Java version as 1.5:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.3.2</version>
<configuration>
<debug>true</debug>
<debuglevel>source,lines,vars</debuglevel>
<optimize>true</optimize>
<source>1.5</source>
<target>1.5</target>
<encoding>UTF-8</encoding>
</configuration>
</plugin>
Could that be the source of the problem? My own project uses
<source>1.7</source><target>1.7</target> to take advantage of the
improvements in Locale.
Does anyone know a solution to this problem? Hopefully it takes no
more than a change in POM...
