Error: Unable to initialize main class com.amazonaws.services.dynamodbv2.local.main.ServerRunner

All working well but today I suddenly get such error
Error: Unable to initialize main class com.amazonaws.services.dynamodbv2.local.main.ServerRunner
Caused by: java.lang.NoClassDefFoundError: org/apache/commons/cli/ParseException

How I could fix this ?

[alejoamiras]

@alexbulakh1994 testing around I found that adding this code fixed it:

DynamoDBLocal.configureInstaller({
  installPath: './dynamodblocal-bin',
  downloadUrl: 'https://s3.sa-east-1.amazonaws.com/dynamodb-local-sao-paulo/dynamodb_local_latest.tar.gz'
});

Actually, having created the installPath folder before, I just needed:

DynamoDBLocal.configureInstaller({
  installPath: './dynamodblocal-bin'
});

But the combination of both parameters made it work without having the folder previously created.

I also got this error in a jest test and was able to fix it by increasing the timeout for this particular test that spins up the DynamoDB-local DB.

To increase the timeout for a jest test see: jestjs/jest#5055 (comment)
