Eclipse 4.7 and Tycho [message #1777445]

Hello everyone, I recently migrated an application from Eclipse 3.7 to Eclipse 4.7 using the Compatibility Layer. Now add the use of Tycho to deploy the application. The application defines target platform and features.
I managed to get all the errors, I only have the following:

No solution found because the problem is unsatisfiable.: [Unable to satisfy dependency from com.zetti.ftpos.features.feature.group 1.0.0.qualifier to com.zetti.ftpos.product.deploy 0.0.0.; Unable to satisfy dependency from org.eclipse.jdt.core 3.13.0.v_OTDT_r260_201706061122 to org.eclipse.objectteams.otdt.core.patch.feature.group [2.0.0,3.0.0).; No solution found because the problem is unsatisfiable.]

I have investigated that it is recommended to add dependency to the parent POM

		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
	</properties>

	</build>

Even so I continue with the same error

Some clue?

Thanks in advance!.

Hi there,

please be aware that this just is a very wild and uninformed guess ... are you sure you really need or want to follow through with "satisfying this dependency"?

i just did search in google with the term "org.eclipse.objectteams.otdt.core.patch" and arrived at https://bugs.eclipse.org/bugs/show_bug.cgi?id=350133

If i understand the comments correctly they talk about an update path in 3.7 which allows for unneeded/-necessary/-wanted installation of said patch feature.

Maybe you could just continue without the burden of satisfying this dependency?

cheers
Daniel

this comments and the surrounding talk might also be helpful

Thanks for answering, I had already read the error that you mention, the problem in this case is that it is the only mistake I have to execute the deployment by Tycho. When throwing the exception the deploy is stopped, that's why I have to fix it.

Best Regards

Please be aware of my humble disclaimer that i do not concern me as someone who should be answering your question ... i am really not well experienced in the workings of tycho ... i merely try to "think alongside" and reply with my thoughts. It would be great if you would get answers from someone more experienced with tycho than myself!

Concerning your problem:
What log does your build produce if you apply the dependency-filter mentioned in https://bugs.eclipse.org/bugs/show_bug.cgi?id=350133#c40 adjusted to the version of jdt.core in your logs?

<plugin>
   <groupId>org.eclipse.tycho</groupId>
   <artifactId>target-platform-configuration</artifactId>
   <version>${tycho-version}</version>
   <configuration>
      <filters>
         <filter>
            <type>eclipse-plugin</type>
            <id>org.eclipse.jdt.core</id>
            <restrictTo>
               <version>3.13.0.v_OTDT_r260_201706061122</version>
            </restrictTo>
         </filter>
      </filters>
   </configuration>
</plugin>

I think i "censored" out a relevant detail and also replaced the version wrong ... i think i put in "offending" plugin-version-stuff instead of the "wanted" plugin version. You probably need to find out the version of org.eclipse.jdt.core like he mentioned - adapt to other release trains (e.g. probably oxygen?) / service releases (e.g. SR1a?) and use that instead of my example.

Also I left out Jans commented advice . Jan mentioned:

<restrictTo>
    <version>3.9.1.v20130905-0837</version>
</restrictTo>

I still think filtering might be able to help you ... but i have no clue how to find out said adapted version.

cheers
Daniel

//edit:
despite my uninitiated guesses you might also try to find help in the tycho-users mailing list. https://accounts.eclipse.org/mailing-list/tycho-user

Thank you very much Daniel !, you were right, I needed to set the jdt.core version correctly.

 <filters>
        <filter>
                  <type>eclipse-plugin</type>
                   <id>org.eclipse.jdt.core</id>
                   <restrictTo>
                   <version>3.13.0.v20170516-1929</version>
                   </restrictTo>
        </filter>
</filters>

I still can not perform the deploy because of the error:
Bundle-ClassPath entry icu-data.jar does not exist in /.m2/repository/p2/osgi/bundle/com.ibm.icu/58.2.0.v20170418-1837/com.ibm.icu-58.2.0.v20170418-1837.jar

Try a couple of tips that they mention in
http://tycho-user.eclipse.narkive.com/1LXKrPt0/nested-jars-in-dependency-issue
But it does not work...
Any clues?.

Best Regards.

Mariano.

To eliminate this error, what I did was add the package to the p2 site generated:

<artifact> <id> com.ibm.icu:icu4j:58.2 </ id> <override> true </ override> </ artifact>

Instead of importing the whole org.eclipse.ui package, what I did was import the specific package that requires e.g. org.eclipse.ui.ide.
I hope it serves someone.

Best Regards.
Mariano.
