Batch files in bin/windows/*.bat do not correctly set CLASSPATH

[brad-gorman]

Hi.

I'm not sure this is exactly the right repo to log this issue against, but it's where the files I'm referring to are. Please point me in the right direction if you'd prefer it was logged elsewhere.

I'm running the downloaded confluent-7.4.1 zip from here and the Windows batch files do not set up the CLASSPATH environment correctly. Running them in a non-development tree results in
source link

    Classpath is empty. Please build the project first e.g. by running 'gradlew jarAll'`

There is no gradlew in the released tools zip. I suspect either running them in a self-compiled development tree works, or most people are not using the Windows batch files.

It looks like they refer to the Apache Kafka style directory structure with \libs\ but the Confluent packages have a slightly different structure.

rem Classpath addition for release
for %%i in ("%BASE_DIR%\libs\*") do (
	call :concat "%%i"
)

The Linux shell scripts set up what they call an LSB-style path in addition to the above, but this is missing on the Windows equivalents
source link

# classpath addition for release
for file in "$base_dir"/libs/*;
do
  if should_include_file "$file"; then
    CLASSPATH="$CLASSPATH":"$file"
  fi
done

# CONFLUENT: classpath addition for releases with LSB-style layout
CLASSPATH="$CLASSPATH":"$base_dir/share/java/kafka/*"
