How to solve org.osgi.framework.BundleException in demo.app

Development Add-ons

Hi,
I’m trying to develop a new binding. For testing and debugging I’m using the org.openhab.demo.app.

Once added dependencies to pom.xml and added my repo to requirements I get the error when launching.

! org.osgi.framework.FrameworkEvent[source=org.openhab.binding.linktap_2.5.4.202005011523 [136]]
org.osgi.framework.BundleException: Could not resolve module: org.openhab.binding.linktap [136]
Unresolved requirement: Import-Package: org.apache.http

I’m using those import in my class manage a REST call to the linktap api.

import org.apache.http.HttpResponse;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.HttpClientBuilder;

Is there an option to resolve the error?

Thanks,
becksen

Don‘t really know how to solv this dependency issue, but you should use


org.eclipse.jetty.client.HttpClient;

instead of apache.

Might be that your version is not correct. Actually you should build against 2.5.5

Hi hmerk,

thanks for your reply. I haven’t found the same capabilities of

org.eclipse.jetty.client.HttpClient;

so far as in org.apache.http. But I’ll have a look at it if I can use it. In addition building against 2.5.5 makes sense, but how to I get upgraded my git project as well as the demo.app to 2.5.5.

Best regards,

You should have two repos in your workspace, openhab2-addons and openhab-distro. In addons repo, you should have several branches, one would be your feature branch, one called 2.5.5
Sync the 2.5.5 branch with the openhab/openhab2-addons branch and then rebase your feature branch against 2.5.5 branch. Dont forget to update your pom to 2.5.5
For the distro, just pull actual changes.

org.eclipse.jetty.client.HttpClient does not provide what is required. Instead I’ve identified okhttp3 which is perfect for the needs.

Also update the POM file:

<!-- https://mvnrepository.com/artifact/com.squareup.okhttp3/okhttp -->
<dependency>
    <groupId>com.squareup.okhttp3</groupId>
    <artifactId>okhttp</artifactId>
    <version>4.6.0</version>
</dependency>

But again the same error :frowning:

! org.osgi.framework.FrameworkEvent[source=org.openhab.binding.linktap_2.5.4.202005031652 [136]]
org.osgi.framework.BundleException: Could not resolve module: org.openhab.binding.linktap [136]
  Unresolved requirement: Import-Package: okhttp3

Maybe it is an eclipse issue, but VSCode seems not be an alternative currently. Any ideas how to get the unresolved dependencies resolved?

I’ve just observed that my openhab2-addons repo might be wrongly configured right?

Origin:
fetch:  https://github.com/openhab/openhab-addons.git
push: https://github.com/becksen/openhab-addons-1.git

upstream:
fetch: https://github.com/becksen/openhab-addons-1.git
push: https://github.com/becksen/openhab-addons-1.git

Can’t find a 2.5.5 branch in the repo.

Regards,
Timmy
