[jcosano]

Hello!

When I'm importing Activiti Engine 5.8 into mi Eclipse Helios I find this error (and project not compile, old versions of activiti always works fine)

Can you help me?

hi
don't use the Eclipse Helios for this purpose (generally ) ,there are a lots of other problems !
Try eclipse indigo
goodLuck

[jcosano]

Ok Solve!

Finally I use Indigo with:

- Subversive
- Maven (using Maven runtime 3.0.3)

And I obtain same error than Helios… with quick fix it suggest install "Tycho project" from sonatype (then I install it)

And now all works fine!

Hi jcosano,

how did you install the tycho project via quick fix? I'm encountering the same problem like you with the current trunk, but I didn't manage to fix it.
After adding tycho the way it is described in the documentation ( http://wiki.eclipse.org/Tycho/Reference_Card ) the problem remains.
I also removed the "*" entry from <activiti.osgi.import.pkg> in the parent pom, but the apache felix maven-bundle-plugin still complains about the default package on the import path.
Does anybody know a solution to this problem?

Thanks in advance,
Klaus

Hi!

I use quick fix option from eclipse (http://wiki.eclipse.org/FAQ_What_is_a_Quick_Fix%3F)

good luck!

[ksperner]

Hi jcosano,

thank you for the quick reply. I know, what a quick fix in Eclipse is, but I don't understand how to apply one in this situation. The error message (which is the one shown in your first post) appears in the Maven Console in the Console View after cleaning the activiti-engine project, but Eclipse doesn't facilitate the usage of a quick fix there. I can apply a quick fix in the markers view or in the editor pane, but there I don't see anything related to maven or tycho.
Do you remember, how you applied the quick fix?

Thanks and best regards,
Klaus

[jcosano]

I remember that quickfix suggest to me that I need install tycho… I accept this, and eclipse download and install automatically this feature.

[ksperner]

Hmm, unfortunately, this does not work for me 😞

Nevertheless, thank you for your help.
