java.lang.NoClassDefFoundError in 3.5.0

See original GitHub issue

When I used the 3.5.0 version of okhttp, I encountered a weird exception Exception in thread “main” java.lang.NoClassDefFoundError: okio/BufferedSource at okhttp3.internal.Util.<clinit>(Util.java:48) at okhttp3.OkHttpClient.<clinit>(OkHttpClient.java:121) at com.demo.okHttp.Demo.main(Demo.java:8) Caused by: java.lang.ClassNotFoundException: okio.BufferedSource at java.net.URLClassLoader.findClass(URLClassLoader.java:381) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) … 3 more however, when I use the 3.2 it works fine. My code is as simple as public static void main(String[] args) { OkHttpClient client = new OkHttpClient(); } and I have okhttp 3.5.0 and okio 1.11.0 imported to my project. Is this a bug in the 3.5.0 version, how can I solve this problem?

you need also download the okio.jar as your project module

@runyan @smileboywtu @kinsleykajiva @Danc2050 I’m creating a java library where I’m using okhttp client and it working fine when tested. The java library will be reused across java applications. But when importing the library as a dependency in other application, I’m getting the same error as above, during the application startup.

Attaching below is dependency added in my library pom.xml. Appreciate your help. <dependency> <groupId>com.squareup.okhttp3</groupId> <artifactId>okhttp</artifactId> <version>4.10.0</version> </dependency>

    <dependency>
        <groupId>com.squareup.okio</groupId>
        <artifactId>okio-jvm</artifactId>
        <version>3.0.0</version>
        <scope>compile</scope>
    </dependency>
