`NoSuchFieldError: Companion` when packaged in WAR

[PeterTrotter]

We've added sib-api-v3-sdk to an older project using Maven served on tomcat 7.

<dependency>
	<groupId>com.sendinblue</groupId>
	<artifactId>sib-api-v3-sdk</artifactId>
	<version>7.0.0</version>
</dependency>

When run with mvn clean tomcat7:run everything seems fine.

Packaged as a war mvn clean tomcat7:run-war it fails with:

Caused by: java.lang.NoSuchFieldError: Companion
	at okhttp3.internal.Util.<clinit>(Util.kt:70)
	at okhttp3.OkHttpClient.<clinit>(OkHttpClient.kt:1073)
	at sendinblue.ApiClient.<init>(ApiClient.java:80)
	at sendinblue.Configuration.<clinit>(Configuration.java:18)

Attaching a debugger and evaluating Configuration.getDefaultApiClient(); gives:

Method threw 'java.lang.NoClassDefFoundError' exception.
Could not initialize class sendinblue.Configuration
sendinblue.Configuration.getDefaultApiClient(Configuration.java:27)

Looking at mvn dependency:tree:

All the jars are present in the war file WEB_INF/lib/ and there don't appear to be differing versions aside from those requested above.

Any suggestions?

It's a frustrating issue and it seems a waste of time to bypass your library and go direct to the API even though we would then get proper typing and far fewer dependencies ;-)

Targeting language level 1.8 on OpenJDK-11

[PeterTrotter]

Please see https://github.com/PeterTrotter/brevo-tomcat-7 as a minimal example of the library failing when run packed in a war file on tomcat 7.

Any thoughts as to what might be causing this / solutions?

[PeterTrotter]

Could you confirm the okio version is as expected:

<dependency>
 <groupId>com.squareup.okio</groupId>
 <artifactId>okio</artifactId>
 <version>1.14.0</version>
 </dependency>

It seems to explicitly conflict with the transitive dependencies of com.squareup.okhttp3:okhttp:jar:4.10.0, specifically com.squareup.okio:okio-jvm:jar:3.0.0.

Is this strongly related to #50 ?

If okio is required it looks like the problem is that the release 6 months ago updated okhttp-version but not okio-version when the two are related.

Please try this way to resolve it:
#1 Install okhttp package
<dependency> <groupId>com.squareup.okhttp3</groupId> <artifactId>okhttp</artifactId> <version>4.9.1</version> </dependency>

#2 Init okthttp with @bean

@Bean
public OkHttpClient okHttpClient() {
	return new OkHttpClient.Builder()
			.readTimeout(60, TimeUnit.SECONDS)
			.connectTimeout(60, TimeUnit.SECONDS)
			.build();
}

Thanks very much for your reply.

Is that the Spring @Bean annotation?

We are not using Spring and the example I gave is the simplest packaging possible of your library on Tomcat (Just 3 small files).

Please let me know which @Bean annotation it is so I can give it a try.

The cleanest fix I have found is to update your dependencies:

<!-- Brevo mailinglist integration -->
<dependency>
	<groupId>com.sendinblue</groupId>
	<artifactId>sib-api-v3-sdk</artifactId>
	<version>7.0.0</version>
	<exclusions>
		<exclusion>
			<groupId>com.squareup.okio</groupId>
			<artifactId>okio</artifactId>
		</exclusion>
	</exclusions>
</dependency>
<dependency>
	<groupId>com.squareup.okio</groupId>
	<artifactId>okio</artifactId>
	<version>3.0.0</version>
</dependency>

Hi all,

Faced the same issue with Spring Boot.

 @Bean
 public ApiClient apiClient(@Value("${brevo.api-key}") String brevoApiKey) {
 ApiClient defaultClient = new ApiClient();
 ApiKeyAuth apiKey = (ApiKeyAuth) defaultClient.getAuthentication("api-key");
 apiKey.setApiKey(brevoApiKey);
 return defaultClient;
 }

Issue is throws on the first line new ApiClient()

Caused by: java.lang.NoSuchFieldError: Class okio.Options does not have member field 'okio.Options$Companion Companion'
	at okhttp3.internal.Util.<clinit>(Util.kt:70)
	at okhttp3.OkHttpClient.<clinit>(OkHttpClient.kt:1073)
	at sendinblue.ApiClient.<init>(ApiClient.java:80)

Fixed by adding maven dependency (#51 (comment))

Funnily, Mailjet does have a similiar problem: mailjet/mailjet-apiv3-java#184

[Rapster]

Problem is still present. Fix as of today is:

 <dependency>
 <groupId>com.sendinblue</groupId>
 <artifactId>sib-api-v3-sdk</artifactId>
 <version>7.0.0</version>
 <exclusions>
 <exclusion>
 <groupId>com.squareup.okio</groupId>
 <artifactId>okio</artifactId>
 </exclusion>
 </exclusions>
 </dependency>
 <dependency>
 <groupId>com.squareup.okio</groupId>
 <artifactId>okio</artifactId>
 <version>3.6.0</version>
 </dependency>

Any chance to make a new minor release to fix that issue plz? @sendinblue @getbrevo

I'd be happy to make a PR if you can make that happen 😄

solved by adding this into dependencies

 <dependency>
 <groupId>com.squareup.okhttp3</groupId>
 <artifactId>okhttp</artifactId>
 <version>4.9.1</version>
 </dependency>
 <dependency>
 <groupId>com.squareup.okhttp3</groupId>
 <artifactId>okhttp-urlconnection</artifactId>
 <version>4.9.1</version>
 </dependency>
 <dependency>
 <groupId>com.squareup.okio</groupId>
 <artifactId>okio</artifactId>
 <version>2.8.0</version>
