“NoSuchMethodErrors” due to multiple versions of com.squareup.okhttp3:okhttp:jar

[Bing-ok]

Hi, there are multiple versions of com.squareup.okhttp3:okhttp in github-api-master. As shown in the following dependency tree, according to Maven's “nearest wins” strategy, only com.squareup.okhttp3:okhttp:4.4.1 can be loaded, and com.squareup.okhttp3:okhttp:3.12.3 will be shadowed.

As com.squareup.okhttp3:okhttp:3.12.3 has not been loaded during the building process, several methods are missing. However, the missing methods:
1. okhttp3.internal.Version: java.lang.String userAgent()

Check for details of invocation

paths------
<org.kohsuke.github.extras.okhttp3.ObsoleteUrlFactory$DelegatingHttpsURLConnection: java.io.OutputStream getOutputStream()> github-api-master\target\classes

<okhttp3.internal.Version: java.lang.String userAgent()>

2. okhttp3.internal.http.HttpDate: java.lang.String format(java.util.Date)

Check for details of invocation

paths------
<org.kohsuke.github.extras.okhttp3.ObsoleteUrlFactory$DelegatingHttpsURLConnection: void setIfModifiedSince(long)> github-api-master\target\classes
<okhttp3.internal.huc.OkHttpURLConnection: void setIfModifiedSince(long)> Repositories\com\squareup\okhttp3\okhttp-urlconnection\3.12.3\okhttp-urlconnection-3.12.3.jar
<okhttp3.internal.http.HttpDate: java.lang.String format(java.util.Date)>

3. okhttp3.internal.platform.Platform: void log(int,java.lang.String,java.lang.Throwable)

Check for details of invocation

paths------
<org.kohsuke.github.extras.okhttp3.ObsoleteUrlFactory$DelegatingHttpsURLConnection: void setRequestProperty(java.lang.String,java.lang.String)> github-api-master\target\classes
<okhttp3.internal.huc.OkHttpURLConnection: void setRequestProperty(java.lang.String,java.lang.String)> Repositories\com\squareup\okhttp3\okhttp-urlconnection\3.12.3\okhttp-urlconnection-3.12.3.jar
<okhttp3.internal.platform.Platform: void log(int,java.lang.String,java.lang.Throwable)>

4. okhttp3.internal.http.StatusLine: okhttp3.internal.http.StatusLine get(okhttp3.Response)

Check for details of invocation

paths------
<org.kohsuke.github.extras.okhttp3.ObsoleteUrlFactory$DelegatingHttpsURLConnection: java.lang.String getHeaderField(java.lang.String)> github-api-master\target\classes
<okhttp3.internal.huc.OkHttpURLConnection: java.lang.String getHeaderField(java.lang.String)> Repositories\com\squareup\okhttp3\okhttp-urlconnection\3.12.3\okhttp-urlconnection-3.12.3.jar
<okhttp3.internal.http.StatusLine: okhttp3.internal.http.StatusLine get(okhttp3.Response)>

The above missing methods are actually referenced by github-api-master, which will cause “NoSuchMethodErrors” at runtime.

Suggested fixing solutions:

1. Upgrade dependency com.squareup.okhttp3:okhttp-urlconnection from 3.12.3 to 4.4.1. Because one conflicting library version com.squareup.okhttp3:okhttp:3.12.3 is transitively introduced by com.squareup.okhttp3:okhttp-urlconnection:3.12.3. Upgrading dependency com.squareup.okhttp3:okhttp-urlconnection from 3.12.3 to 4.4.1 can solve this dependency conflict.
2. Change dependency com.squareup.okhttp3:okhttp from 4.4.1 to 3.12.3.

Please let me know which solution do you prefer? I can submit a PR to fix it.

Thank you very much for your attention.
Best regards,

Could you help me review this issue? 👍 Thanks! @bitwiseman

Suggested fixing solutions:

1. Upgrade dependency com.squareup.okhttp3:okhttp-urlconnection from 3.12.3 to 4.4.1. Because one conflicting library version com.squareup.okhttp3:okhttp:3.12.3 is transitively introduced by com.squareup.okhttp3:okhttp-urlconnection:3.12.3. Upgrading dependency com.squareup.okhttp3:okhttp-urlconnection from 3.12.3 to 4.4.1 can solve this dependency conflict.
2. Change dependency com.squareup.okhttp3:okhttp from 4.4.1 to 3.12.3.

Neither of these. This setting is by design.

These are optional dependencies. com.squareup.okhttp3:okhttp-urlconnection is deprecated, but retained for compatibility.

If a down stream project wants to use com.squareup.okhttp3:okhttp-urlconnection they can do so my forcing com.squareup.okhttp3:okhttp in their project to 3.12.3 (using dependencyManagment).

Option 1 would break compatibility, option 2 would downgrade behavior.

Thanks for your support! What do you suggest to solve this problem?

@Bing-ok
Dependency management allows you to exclude dependencies or force them to versions you want.
https://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html#dependency-management

I assume that you are trying to use com.squareup.okhttp3:okhttp-urlconnection. I strongly suggest that you use the Client class of com.squareup.okhttp3:okhttp if possible. com.squareup.okhttp3:okhttp-urlconnection is deprecated and unsupported.

Putting that aside, here's how you can fix the dependency tree problem you're seeing.

You can do this:

  <dependencies>
     <dependency>
       <groupId>com.squareup.okhttp3</groupId>
       <artifactId>okhttp-urlconnection</artifactId>
       <version>3.12.12</version>
    </dependency>
    <dependency>
      <groupId>org.kohsuke</groupId>
      <artifactId>github-api</artifactId>
      <version>1.116</version>
      <exclusions>
        <exclusion>
          <groupId>com.squareup.okhttp3</groupId>
          <artifactId>okhttp</artifactId>
        </exclusion>
        <exclusion>
          <groupId>com.squareup.okhttp3</groupId>
          <artifactId>okhttp-urlconnection</artifactId>
        </exclusion>
      </exclusions>
    </dependency>
  </dependencies>

Or you can something like this:

  <dependencyManagement>
    <dependencies>
       <dependency>
         <groupId>com.squareup.okhttp3</groupId>
         <artifactId>okhttp</artifactId>
         <version>3.12.12</version>
      </dependency>
       <dependency>
         <groupId>com.squareup.okhttp3</groupId>
         <artifactId>okhttp-urlconnection</artifactId>
         <version>3.12.12</version>
      </dependency>
    </dependencies>
  </dependencyManagement>
  <dependencies>
     <dependency>
       <groupId>com.squareup.okhttp3</groupId>
       <artifactId>okhttp-urlconnection</artifactId>
    </dependency>
    <dependency>
      <groupId>org.kohsuke</groupId>
      <artifactId>github-api</artifactId>
      <version>1.116</version>
    </dependency>
  </dependencies>
