This answer did not help.
Update
This works
testImplementation 'org.testcontainers:testcontainers:1.15.0-rc2' testImplementation "org.testcontainers:junit-jupiter:1.15.0-rc2" testImplementation 'org.testcontainers:kafka:1.15.0-rc2' 1 Answer
The static parse method was only added to the testcontainers library back in July. You're using version 1.14.3, which was released in May. I expect that if you upgrade the version of the library to a 15.X (version 1.15.0-rc2 seems to be the latest), I expect your problem will be resolved.
Alternately, you can change your usage of that library to what it was capable of in version 1.14.3.
UPDATE: I just saw (and finally understood) @tgdavies's suggestion that you can just call the DockerImageName object's constructor directly via:
return new DockerImageName(fullImageName);
