com.squareup.okio okio 2.8.0

In Java programming, encountering the error 'java.lang.NoSuchFieldError: Companion' is not uncommon. This issue typically arises due to an incompatible version of the 'com.squareup.okio' library used in the project.

To resolve this problem, the first step is to check the project's dependencies. Ensure that the correct version of the 'com.squareup.okio' library is added in the project's 'pom.xml' or 'build.gradle' file. In this case, we are using version '2.8.0'. Make sure this version exists and is compatible with other dependencies.

Additionally, you can try forcing a refresh of dependencies in the project build tool to ensure you are using the latest library version. If the issue persists, consider lowering the version of the 'com.squareup.okio' library until a version compatible with other libraries in the project is found.

Such errors often involve the removal or renaming of classes or methods in the library, making the corresponding field unfindable. Therefore, updating library versions promptly is an effective approach to resolving such issues.
