Everything else is just a warning. {noformat} [javac] /home/ubuntu/cassandra/src/java/org/apache/cassandra/utils/Throwables.java:80: error: unreported exception Exception; must be caught or declared to be thrown [javac] perform(Stream.of(actions)); [javac] ^ {noformat} Seems like javac isn't able to infer the types. Using an explicit declaration for the Stream.of() value will fix this. But now I'm getting [another issue|https://circleci.com/gh/spodkowinski/cassandra/123#tests/containers/3] saying that {{MoreExecutors.sameThreadExecutor())}} cannot be found. This seems to be due to [#492|https://github.com/google/error-prone/issues/492]. Again, the newer guava version used by errorprone breaks the build. -Why this isn't the case on my local machine is still beyond me; classpath issues I guess..- Edit: solved, use {{ant realclean}} was (Author: spo...@gmail.com): The javac error that causes ant to fail is the following.

See attachments for results. > Unfortunately there are still some issues on how the analyzer is effecting > generated code and used guava versions, see > [#492|https://github.com/google/error-prone/issues/492]. In case those issues > have been solved and the resulting code isn't affected by the analyzer, I'd > suggest to add it to trunk with warn only behaviour and some less useful > checks disabled. Alternatively a new ant target could be added, maybe with > build breaking checks and CI integration. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
