zxing jigsaw modules package name conflict

[daniel ritter]

I've got a problem to use the modules 'core' & 'javase' in the same application module cause both modules have the package 'com.google.zxing'. So my IDE shows a warning(see attachment). Here is my maven import for zxing:

<!-- https://mvnrepository.com/artifact/com.google.zxing/core -->
<dependency>
<groupId>com.google.zxing</groupId>
<artifactId>core</artifactId>
<version>3.3.1</version>
</dependency>

<!-- https://mvnrepository.com/artifact/com.google.zxing/javase -->
<dependency>
<groupId>com.google.zxing</groupId>
<artifactId>javase</artifactId>
<version>3.3.1</version>
</dependency>

Is there a smart way to solve this package name conflict?

Sorry to say that the project is not going to be compatible with the Java 9 module requirements for exactly this reason. Several artifacts declare classes in the same package, and that's not allowed. If we put it together today of course we couldn't do that, but it can't be changed without breaking compatibility, and it's not worthwhile. The project still works fine in Java 9, just can't use its module declarations.
