Hi folks,

I tried to build Papyrus 4.0.0-M6 on Eclipse Photon these days, but failed with many errors. Among them, there are some caused by the incorrectly-set version attributes of import-packages in many manifest files (MANIFEST.MF).

The error descriptions are like this:

'com.google.common.base' dependency must specify a version range...

However, currently the manifest file of project org.eclipse.papyrus.infra.core (and more others) is written as:

Import-Package: com.google.common.base;version="21.0.0",...


Please see the screenshot in the attachment for details. I guess version ranges like [21.0.0,...) should be used here.

Is this a bug? If it is, hope it could be fixed soon.

Thanks!

Hi,

I don't have the error.
Did you change the pde compiler option with more aggressive checks ?
(Window > Preference > Plug-in Development > Compiler

Or did you install some tooling to check Manifest?
(It's recommended to use range but not required)

It's very unlikely that we will use version range for Guava (which includes com.google.common ...)
Main reasons:
- Guava is evolving a lot faster than release train (See https://github.com/google/guava/releases )
- we already got many issues with Guava ranged version (See Bugs Papyrus Guava)

IMHO: time spent around Guava should be used to replace it (if possible) by Java 8/9 newest API

Regards
Benoit
