Import OkHttp to Liferay 7.4

Question

I made a Liferay 7.4 Service-Builder module, in which I needed to import okhttp3. First, I wrote in build.gradle:

compileInclude 'com.squareup.okhttp3:okhttp:4.10.0'

Then the Gradle build process produced an error:

error  : Classes found in the wrong directory: {META-INF/versions/9/module-info.class=module-info}

After that I changed the build.gradle line to:

compile 'com.squareup.okhttp3:okhttp:4.10.0'

The build process passed, but in deployment there was an exception:

com.liferay.portal.kernel.log.LogSanitizerException: org.osgi.framework.BundleException: Could not resolve module: com.toptoken.core.service [1610]_  Unresolved requirement: Import-Package: okhttp3_ [Sanitized]

How can I import the okhttp3 library without errors?

My Java version is 11.

Adding Import-Package: okhttp3;version="[4.10,5)" or Require-Bundle: okhttp3;version="[4.10,5)" to bnd.bnd didn't work.

I had the same problem with a poi library, it worked for me by adding the line -fixupmessages: Classes found in the wrong directory: ...;is:=ignore in the bnd.bnd file, leave the compileInclude so the resources are part of your jar file.
