   The straightforward way of running a Java benchmark is through the following command:
   ```
   java  -jar ./performance/target/benchmarks.jar 
   ```
   However, it is like to fail with the following message:
   
   ```
   ERROR: Unable to find the resource: /META-INF/BenchmarkList
   ```
   
   The fundamental reason for this error is missing some jars in the class path, and it is considered a bug of maven compilation plugin (https://issues.apache.org/jira/browse/MCOMPILER-369)
   
   Since there are many jars required (directly or indirected referenced), we recommend running the benchmarks through maven.
   
   To run all benchmarks, please go to the arrow-performance directory, and invoke the command:
   
   ```
   mvn clean install -Dskip.perf.benchmarks=false
   ```
   
   We also support filtering specific benchmarks, for example:
   ```
   mvn clean install -Dskip.perf.benchmarks=false -Dbenchmark.filter=.*IntBenchmarks.setIntDirectly
   ```
   In addtion, we also support configuring other benchmark parameters, for example:
   ```
   mvn clean install -Dskip.perf.benchmarks=false -Dbenchmark.filter=.*IntBenchmarks.setIntDirectly -Dbenchmark.forks=1 -Dbenchmark.warmups=5 -Dbenchmark.runs=5
   ```
