[Xpand] MWE2 Workflow fails with package uri not found [message #1311456] Wed, 23 April 2014 20:25 Go to next message

Hi, I am new to Xpand and falling at the first hurdle :(

I have modified the example MWE and MWE2 workflows to try my own model
and both fail with something like:

80 ERROR Mwe2Launcher - Problems running workflow
xpand.example.Generator: Couldn't load resource under
platform:/resource/com.test.xpand/src/Test.xmi :
org.eclipse.emf.ecore.xmi.PackageNotFoundException: Package with uri
'http://my.test.com/1.0' not found.
(platform:/resource/com.test.xpand/src/Test.xmi, 2, 180)

In my Test.xmi file there is a reference to the http://my.test.com/1.0 uri:

xmlns:com.test="http://my.test.com/1.0"

In the manifest.mf for my Xpand generator project I have added my EMF
project as a dependancy:

Require-Bundle: org.eclipse.jdt.core;bundle-version="3.5.0",
org.eclipse.xtend.profiler;resolution:=optional,
...,
com.test.emf;bundle-version="1.0.0"


And within the plugin.xml of the EMF project the following extension
point uses this URI:

<extension point="org.eclipse.emf.ecore.generated_package">
<!-- @generated TEST -->
<package
uri="http://my.test.com/1.0"
class="com.test.TestPackage"
genModel="model/Test.genmodel"/>
</extension>

Thanks to any one who can help me figure out what I am missing from my
setup?

Nigel

Hi Christian,

thanks for helping, my MWE file looks like the following:

<?xml version="1.0"?>
<workflow>
<property name="jad" value="com.test.xpand/src/Test.xmi" />
<property name="src-gen" value="src-gen" />

<!-- set up EMF for standalone execution -->
<bean class="org.eclipse.emf.mwe.utils.StandaloneSetup" >
<platformUri value="../"/>
</bean>

<!-- instantiate metamodel -->
<bean id="mm_emf"
class="org.eclipse.xtend.typesystem.emf.EmfRegistryMetaModel" />

<!-- load model and store it in slot 'model' -->
<component class="org.eclipse.emf.mwe.utils.Reader">
<uri value="platform:/resource/${jad}" />
<modelSlot value="jad" />
</component>

<!-- Clear output directory -->
<component class="org.eclipse.emf.mwe.utils.DirectoryCleaner">
<directory value="${src-gen}"/>
</component>

<!-- generate code -->
<component class="org.eclipse.xpand2.Generator">
<metaModel idRef="mm_emf"/>
<expand
value="template::JADTemplate::main FOR jaf" />
<outlet path="${src-gen}" />
<resourceManager class
="org.eclipse.xtend.expression.ResourceManagerDefaultImpl">
<fileEncoding value="UTF-8"/>
</resourceManager>
</component>
</workflow>

It is based on the example file.

Hi Christian,

thanks for the suggestion about registering the package in the
standalone set up... a bit more research in this area showed me that I
was missing the following:

<bean class="org.eclipse.emf.mwe.utils.StandaloneSetup" >
<platformUri value="../"/>
<registerEcoreFile
value="platform:/resource/com.test.emf/model/Test.ecore" />
</bean>

Thanks!

Hi

If you install the MWE2 language feature you get a nice Xtext editor for
MWE and don't have to work within <>'s.

Hi Ed,

I've installed the MWE2 plugins and they have made my MWE files easier
to read but my Xpand file is now showing as having errors everywhere? Is
there a validator being triggered that should not be?

BTW I also found if I try and uninstall these plugins my eclipse hangs
on restart trying to load org.eclipse.xtext.ui.shared. I guess they pull
out a dependency they should not :(

Any advice on the former part welcome, as the editor makes life a lot
simpler.

Nigel
