Maven-与JavaME，JavaSE和Android模块共享多模块项目的记录器

Question

Short introduction:

My task is to create a multi-module project (for which I chosen Maven) with modules for JavaME and Android. More specifically: I'm creating application for phones and my boss obliged me to make a project with shared common code (BTW: I think he puts too much pressure on sharing code between JavaME and Android - these two being based on Java language doesn't mean that sharing code between them is easy).

Problem:

I have three modules:

• common - this is written against JavaSE 1.1 so it doesn't need emulator to test it and also JavaME would be able to use that module,
• jme - this is written against JavaME 2,
• android - this is (yet to be) written against Android,

I want to have three different loggers, one for each module, which share common interface and maybe the logger for common module could be a base (class) for the two other loggers. The common classes should use the same logger that the module that incorporates them or a third version of logger for purposes of compiling and testing that common module separately.

Question:

How to configure Maven so that it would include different versions of logger class when compiling & testing different modules? Or maybe you have different proposals?

Update:

Right now I have my own logger for JavaME which uses RecordStore to store logs and has easy way to retrieve a specified continuous range of logs, convert them to JSON, HTML and text and then send them in batch by email. Additionally it periodically removes old records from RecordStore. I would want to keep such functionality, ie. easy way to retrieve and transform log records.

Answer 1

For the testing you can simply achieve that using the appropriate src/test/resources folder to put the configuration for the logging system into and in your pom you could define different logging system in the different areas

   +-- pom.xml
        +--- common (pom.xml)
        +--- jme (pom.xml)
        +--- android (pom.xml)

and you can define in common (pom.xml) a different logging system than in jme (pom.xml) as dependency (scope: test). I'm not sure if this will help you but the problem with different logging frameworks has already been solved by slf4j .
