ExecuteGroovyScript: The following classes appear as argument class and as parameter class, but are defined by different class loader

Just trying to use a simple Groovy Script for setting TTL on redis keys with a given pattern.

@Grab(group='org.springframework.data', module='spring-data-redis', version='2.6.2') import org.springframework.data.redis.connection.RedisConnection import org.springframework.data.redis.core.ScanOptions def pool = CTL.redis.getConnection() pool.withCloseable {conn-> def keyPattern = 'raw:extra:*' def scanOptions = ScanOptions.scanOptions().match(keyPattern).build() def cursor = conn.keyCommands().scan(scanOptions) while(cursor.hasNext()) { def key = cursor.next() // Check if the key has a TTL if(conn.keyCommands().pTtl(key) == -1) { // Set a 15 days TTL for the key conn.keyCommands().expire(key, 15 * 24 * 60 * 60) } } }

However this is giving this specific error. I tried using KeyScanOptions, without grabbing the spring-data-redis and a builder. Still getting the same error.

I checked the folder and it has spring-data-redis:2.6.2 under this one. I also tried using keys for key lookup and it works but I don't want to use keys for performance reasons. Other functions are working fine but just ScanOptions is giving this specific error.

Did you try what the error says?

Possible solutions: scan(org.springframework.data.redis.core.KeyScanOptions)
