Cassandra: Error opening zip file or JAR manifest missing : D:\cassandra\lib\jamm-0.3.2

Question

Been trying to build Apache Cassandra using Ant. The build is successful, but the Cassandra server won't start using bin\cassandra because of the error: Error opening zip file or JAR manifest missing: D:\cassandra\lib\jamm-0.3.2 .

Here is the environment setup:

• JDK 8 bin directory added to PATH
• JAVA_HOME is set to the JDK 8 directory
• CASSANDRA_HOME is set to D:\cassandra, where I cloned the repo
• D:\cassandra\lib\jamm-0.3.2.jar exists

Just in case I tried recloning the repo in another directory, rebuilding, but same error.

Checking the output when building, I noticed warnings like this one, I don't know if it is relevant.

[artifact:dependencies] [WARNING] POM for 'org.perfkit.sjk.parsers:sjk-jfr5:pom:
0.5:compile' is invalid.
[artifact:dependencies]
[artifact:dependencies] Its dependencies (if any) will NOT be available to the c
urrent build.

Any idea of what else I could test? Thank you.

Answer 1

I've seen this issue, too, when running Cassandra from my build directory.

What you'll want to do is to "deploy" your build (target) to a different directory, and set your CASSANDRA_HOME to that. Essentially, you'll want to emulate the how the "delivered" directory structure looks, ensuring that subdirs like bin/ , conf/ and lib/ are at the same directory level.

Try that and see if it helps.

I forgot to mention that I set the environment variables PATH, CASSANDRA_HOME and JAVA_HOME using the set command.

By going to the system parameters and changing the user variables, it worked. I changed those three at the same time so I am not sure which one was blocking.
