java.lang.NoSuchMethodError when using lettuce 6.x

[xenomachina]

It looks like lettuce 6.x introduced a binary incompatibility that makes ratelimitj break at runtime.

The breakage we're running into is that RedisScriptLoader calls RedisScriptingReactiveCommands.scriptLoad, and this changed from being a single method with the signature Mono<String> scriptLoad(V script) to a pair of methods, Mono<String> scriptLoad(String script) and Mono<String> scriptLoad(byte[] script).

This change appears to be source compatible with ratelimitj. I tried changing ratelimitj's dependency on lettuce from io.lettuce:lettuce-core:5.3.4.RELEASE to io.lettuce:lettuce-core:6.0.2.RELEASE, and ./gradlew ratelimitj-redis:check builds and passes with the new version of lettuce.

I think this has been already covered by

From this to this and is available from 0.7.0 release on.

I have the same problem. 0.7.0 Incompatible with lettuce-core:5.3.7.

es.moki.ratelimitj.redis.request.RedisScriptLoader.loadScript()

java.lang.NoSuchMethodError: io.lettuce.core.api.reactive.RedisScriptingReactiveCommands.scriptLoad(Ljava/lang/String;)Lreactor/core/publisher/Mono;

I compared the two versions(ratelimitj-redis 0.7.0-RC3 / 0.7.0) and found that they were basically the same. Except this:

.retry(1, RedisSlidingWindowRequestRateLimiter::startWithNoScriptError)

.retryWhen(Retry.max(1).filter(RedisSlidingWindowRequestRateLimiter::startWithNoScriptError))

ratelimitj-core doesn't change anything.

But if you run it(ratelimitj-redis:0.7.0) in source code, it works.

I think it(NoSuchMethodError) should not be affected by dependencies.

I wonder what caused it.

The incompatibility with lettuce-core 6.x was fixed in f37eb87, when the dependency on lettuce-core was upgraded from 5.3.4 to 6.0.2, so this issue is resolved as reported.

However, the fix means that users of ratelimitj need to also upgrade lettuce-core 6.x.

@sycz I don't know about now, but back when I reported this issue, the incompatibility wouldn't bite you if you built ratelimitj yourself, because the change that was made to lettuce-core was still source-compatible with ratelimitj, just not binary compatible with anything that used the scriptLoad method from the "wrong" version. Can you upgrade your lettuce-core dependency to 6.x? (The current release is 6.1.8.)
