I get compile errors when compiling valid code against a Java model enhanced with JDO. I am confused at the errors because there is no direct usage of the package private static member interfaces in question from Scala. I understand Scala doesn't support using such interfaces from Scala code, but I am confused that the Scala compiler complains about them.

Here is the error I am getting:

[scalac] Compiling 3 scala and 196 java source files to C:\Users\AlainODea\Documents\Project\build\model\tests
   [scalac] error: error while loading Error, Missing dependency 'class javax.jdo.spi.PersistenceCapable$ObjectIdFieldSupplier', required by C:\Users\AlainODea\Documents\Project\model\dist\model.jar(com/example/model/error/Error.class)

   [scalac] 7 errors found

Here is the Ant snippet I use to compile:

<target name="compile" depends="jar">
    <depend srcdir="src" destdir="${src.classes.dir}" cache="${build.dir}/src_dependencies" />
    <scalac srcdir="src" destdir="${src.classes.dir}" classpathref="src.build.classpath">
        <include name="**/*.scala"/>
        <include name="**/*.java"/>
    </scalac>
    <javac srcdir="src" destdir="${src.classes.dir}" source="1.6" target="1.6" nowarn="on"
           debug="on" encoding="UTF-8" classpathref="src.build.classpath" />
</target>

model.jar with the enhanced classes is on src.build.classpath.

I don't understand why scalac cares about dependencies of Java classes it can't resolve if they don't affect the knowledge to compile my Scala source.

Interestingly IntelliJ's Scala Plug-in is able to compile and run this code.

An unfortunate, but passable workaround is to keep the unenhanced class files around to use during the build of dependent modules.

This seems to be a special case with the failing classes mentioned. I have not yet successfully produced a minimal test case, but I am working on it :)

I tried to reproduce this at varying levels without success. I can only reproduce it with a large segment of our proprietary code and framework in place. It seems to be a very involved corner-case of binary dependency analysis of a complex JDO-based data model.

I am willing to do further testing to determine root cause, but I need advice on debugging the Scala compiler.

It could be a duplicate of #1879 or you need to put the jar containing javax.jdo.spi.PersistenceCapable$$ObjectIdFieldSupplier on the classpath for compilation.

It is hard to tell without a reproducible example.
