LinkageError after adding javax.ws.rs-api to Gradle build in Spring Boot 3.2 Kotlin project

Initial Error:

Encountered a NoClassDefFoundError when building with Docker Java API on a spring boot "3.2.1" Kotlin 1.9.21 project

java.lang.NoClassDefFoundError: javax/ws/rs/core/Configuration
    at com.github.dockerjava.jaxrs.JerseyDockerHttpClient$Builder.build(JerseyDockerHttpClient.java:124)
    at com.github.dockerjava.core.DockerClientBuilder.build(DockerClientBuilder.java:106)
    ...

Attempted Solution:

Added the javax.ws.rs-api dependency to my .kts file:

implementation("javax.ws.rs:javax.ws.rs-api:2.1.1")

New Error After Adding Dependency:

Encountered a LinkageError related to ClientBuilder.

java.lang.LinkageError: ClassCastException: attempting to cast jar:file:/home/alkaphreak/.gradle/caches/modules-2/files-2.1/javax.ws.rs/javax.ws.rs-api/2.1.1/d3466bc9321fe84f268a1adb3b90373fc14b0eb5/javax.ws.rs-api-2.1.1.jar!/javax/ws/rs/client/ClientBuilder.class
    at javax.ws.rs.client.ClientBuilder.newBuilder(ClientBuilder.java:81)
    at com.github.dockerjava.jaxrs.JerseyDockerHttpClient.<init>(JerseyDockerHttpClient.java:257)
    ...

Build Script (build.gradle.kts):

// Relevant parts of the build script
dependencies {
    // Other dependencies...
    implementation("com.github.docker-java:docker-java:3.3.4")
    implementation("com.github.docker-java:docker-java-transport-httpclient5:3.3.4")
    implementation("javax.ws.rs:javax.ws.rs-api:2.1.1")
}

Resolution Attempts :

Tried using a resolutionStrategy to force the version without success.

// Apply a resolution strategy to force a single version of the dependency
configurations.all {
    resolutionStrategy {
        // Force usage of a specific version of 'javax.ws.rs-api'
        force("javax.ws.rs:javax.ws.rs-api:2.1.1")
    }
}

Request for Help:

I'm unable to resolve the LinkageError after adding the javax.ws.rs-api dependency. If anyone has insights or suggestions on how to fix this issue, please advise.

Solution

  • To make it work, we can replace the code :

    private fun dockerClient(): DockerClient = DockerClientBuilder
        .getInstance()
        .build()

    By :

    private fun dockerClient(): DockerClient = DockerClientBuilder
        .getInstance()
        .withDockerCmdExecFactory(NettyDockerCmdExecFactory())
        .build()

    Note that withDockerCmdExecFactory is deprecated. I will try to improve that.
