Handler dispatch failed: java.lang.VerifyError: Bad type on operand stack

[bencoepp]

Hi, trying to implement via Maven but get this quite bissare error when trying to init the Class. The Solutions provided by the Readme.md were not helpful.

pom.xml

<dependency>
    <groupId>org.gitlab4j</groupId>
    <artifactId>gitlab4j-api</artifactId>
    <version>5.2.0</version>
</dependency>
<dependency>
    <groupId>javax.ws.rs</groupId>
    <artifactId>javax.ws.rs-api</artifactId>
    <version>2.0.1</version>
</dependency>
<dependency>
    <groupId>org.glassfish.jersey.core</groupId>
    <artifactId>jersey-client</artifactId>
    <version>3.1.2</version>
</dependency>

Implementation

try (GitLabApi gitLabApi = new GitLabApi("https://SOMEURL", "TOKEN")) {
    org.gitlab4j.api.models.Project projectSpec = new org.gitlab4j.api.models.Project()
            .withName(project.getTitle())
            .withDescription(project.getDescription())
            .withIssuesEnabled(false)
            .withMergeRequestsEnabled(true)
            .withWikiEnabled(false)
            .withSnippetsEnabled(true)
            .withPublic(true);

    org.gitlab4j.api.models.Project newProject = gitLabApi.getProjectApi().createProject(projectSpec);
}

Error Output

I hope that someone might be able to answer my question what exactly I did wrong here. Thank you all for your attention.

Hi @BenCoepp, You are mixing Jersey 3.1 (EE10) which requires Jakarta REST 3.1 API with very old 2.0.1 API (from EE 7). Note that the maven artifact changed from javax.ws.rs to jakarta.ws.rs.

If you have any further issues, please file the issue on the Jersey project not here. This is the API project that deals with the issues in the API and the Spec.
