org.icyphy.linguafranca.diagram has build errors concerning EdgeStraighteningStrategy #43

Closed cxbrooks closed 4 years ago

cxbrooks commented 4 years ago

In org.icyphy.linguafranca.diagram, after updating Eclipse with Kieler Lightweight Diagrams - Developer Resources and Examples from http://rtsys.informatik.uni-kiel.de/~kieler/updatesite/ and added all of Elk from https://build.eclipse.org/modeling/elk/updates/nightly, I'm still seeing build errors in

org.icyphy.linguafranca.diagram/src/org/icyphy/linguafranca/diagram/synthesis/LinguaFrancaSynthesis.xtend

Description Resource Path Location Type org.eclipse.elk.alg.layered.p4nodes.bk.EdgeStraighteningStrategy cannot be resolved to a type. LinguaFrancaSynthesis.xtend /org.icyphy.linguafranca.diagram/src/org/icyphy/linguafranca/diagram/synthesis line: 33 /org.icyphy.linguafranca.diagram/src/org/icyphy/linguafranca/diagram/synthesis/LinguaFrancaSynthesis.xtend Xtend Problem

the first is caused by

import org.eclipse.elk.alg.layered.p4nodes.bk.EdgeStraighteningStrategy

the second by

rootNode.setLayoutOption(LayeredOptions.NODE_PLACEMENT_BK_EDGE_STRAIGHTENING, EdgeStraighteningStrategy.IMPROVE_STRAIGHTNESS)

Should these lines be commented out?

I updated xtext/README.md to include instructions for updating Eclipse with the Kieler plugins/features. Perhaps I'm missing the correct steps?

I had the same problem. I will forward the fix from Kiel, which worked for me…

It turns out that it is necessary to rebuild by hand to get the updated KIELER plug-ins. Below are instructions:
