Hello,

I had a problem when i wanted to build my own plugin using buckminster.
with xtext version 2.7.3 evertything works great. but with 2.8.0 and 2.8.1 the dependencies are not included in the plugin. what means that i have to install xtext on every eclipse that i want to install my DSL plugin on.

for this project i will stay with version 2.7.3 but i thought i would let you know.

regards.

Hi

do you mean that you create a p2 site for your plugins and you can't
install your plugins from that p2 site because Xtext dependencies are
not automatically installed as well? You might add Xtext dependencies
as requirements in your installable features (add them as dependencies
in the feature, don't add them as included features, or they will be
part of your p2 site, which I guess you don't want); IIRC Xtext provides
xtext.redist feature for that.

hope this helps
Lorenzo

Hi,

Thanks for your reaction!
That is exactly what I mean. With 2.7.3 I have written the following in my Manifest.mf

Require-Bundle: org.eclipse.xtext;bundle-version="2.7.3";visibility:=reexport,
 org.eclipse.xtext.xbase;resolution:=optional;visibility:=reexport,
 org.eclipse.xtext.generator;bundle-version="2.7.3",
 org.apache.commons.logging;bundle-version="1.0.4";resolution:=optional,
 org.eclipse.emf.codegen.ecore;resolution:=optional,
 org.eclipse.emf.mwe.utils;resolution:=optional,
 org.eclipse.emf.mwe2.launch;resolution:=optional,
 org.eclipse.xtext.util;bundle-version="2.7.3",
 org.eclipse.emf.ecore,
 org.eclipse.emf.common,
 org.antlr.runtime,
 org.eclipse.xtext.common.types;bundle-version="2.7.3",
 org.objectweb.asm;bundle-version="[5.0.1,6.0.0)";resolution:=optional
Import-Package: org.apache.log4j,
 org.eclipse.xtext.xbase.lib

So when I put everything under "Import-package" it should work?

ps.

Your book example hello.buckminster didnt work for me, at least, either.

I was talking about installable IU, that is, feature.xml, not
MANIFEST.MF of a plugin.

Moreover, IIRC, Import-Package requirements are not automatically
considered by p2, which considers only Require-Bundle (but again, I'm
not sure of this).

It does not work as it is with Xtext 2.8.1? Or have you modified
something in it?

cheers

Hello,

thanks for your reply.
there is notthing wrong with the example. but when i install it the Xtext dependencies are not automatically installed.
with xtext 2.7.3 it included the xtext plugins automaticaly but not with 2.8.1.
so I need to add them in feature.xml? where I didnt have to add anything in 2.7.3

regards.

I'd try to add dependencies in the feature.xml (again, as dependencies
not as included features); but just to make sure I understand your
problem: you say that dependencies are not automatically installed... do
you get an error about that? Or you noticed that they are not installed?
Or you can't install your plugins?

Hi

See my earlier reply. If you are using post Luna code you must use
post-Luna P2 repos.

Ok, I suspected that :)
That has nothing to do with the building, it's just that Xtext 2.8.0 is
not present in the Luna update site; you first need to add the Xtext
update site in your Eclipse (you don't need to install anything
manually, just add the Xtext update site), and then you're able to
install your plugins (make sure that "Contact all update sites" is checked).

Hope this clarifies the question.

cheers
Lorenzo

Alternatively, you can configure your update site to include all necessary dependencies:

	<build>
		<plugins>
			<plugin>
				<groupId>org.eclipse.tycho</groupId>
				<artifactId>tycho-p2-repository-plugin</artifactId>
				<version>${tycho.version}</version>
				<configuration>
					<includeAllDependencies>true</includeAllDependencies>
				</configuration>
			</plugin>
		</plugins>
	</build>

If you're using tycho to build your DSLs/update site, that is.
