You can use Maven to download dependencies of Java packages without creating a Java project.
For example,
if you want to download all dependencies of arrow-jvm and arrow-memory
and build everything into a single fat jar (for easy use in other places),
you can first crate a file pom.xml containing the following content
and then run the command mvn assembly:single.
Please refer to
arrow_fat_jar
for more details and the built fat JAR.
