I installed logstash on a debian OS and then installed the Google Pub Sub plugin . Simple pipeline test works fine, but using Google pub/sub as input results in below error. last line of stacktrace: [ERROR] 2018-05-15 20:48:06.544 [LogStash::Runner] Logstash - java.lang.NoSuchMethodError: com.google.common.base.Preconditions.checkArgument(ZLjava/lang/String;J)V sudo bin/logstash --version logstash 6.2.4 /usr/share/logstash$ sudo bin/logstash -f gcp-pubsub-logstash.conf --config.reload.automatic WARNING: Could not find logstash.yml which is typically located in $LS\_HOME/config or /etc/logstash.

It looks like Logstash reverted their guava version between 6.2.3 to 6.2.4. Here's the commit that I think did it: [https://github.com/elastic/logstash/commit/a425a422e03087ac34ad6949f7c95ec6d27faf14](https://github.com/elastic/logstash/commit/a425a422e03087ac34ad6949f7c95ec6d27faf14) The [1.1 version imports guava 19](https://mvnrepository.com/artifact/com.google.googlejavaformat/google-java-format/1.1) and the [1.5 version imports Guava 22](https://mvnrepository.com/artifact/com.google.googlejavaformat/google-java-format/1.5). It looks like `google-java-format` imports it was [reverted because it imports `javac-shaded`](https://github.com/elastic/logstash/pull/9358) which is GPL licensed. Here's the JARs I find in the docker images: ```auto user@elasticstack:~$ docker run -it docker.elastic.co/logstash/logstash:6.2.3 bash WARNING: IPv4 forwarding is disabled. Networking will not work. bash-4.2$ find . | grep guava ./logstash-core/lib/jars/guava-22.0.jar bash-4.2$ ``` ```auto user@elasticstack:~$ docker run -it docker.elastic.co/logstash/logstash:6.2.4 bash WARNING: IPv4 forwarding is disabled. Networking will not work. bash-4.2$ find . | grep guava ./logstash-core/lib/jars/guava-19.0.jar bash-4.2$ ``` We have an [open issue in the Logstash plugin repository](https://github.com/logstash-plugins/logstash-input-google_pubsub/issues/34) and a [PR](https://github.com/logstash-plugins/logstash-input-google_pubsub/pull/36#issuecomment-389597281). ---
