[GitHub] [arrow] rkennedy-mode commented on issue #37892: Offer an un-shaded version of the Flight SQL JDBC driver
rkennedy-mode commented on issue #37892:
URL: https://github.com/apache/arrow/issues/37892#issuecomment-1737968363
As a test, I made the following change to the `flight-sql-jdbc-driver` POM:
```diff
diff --git a/java/flight/flight-sql-jdbc-driver/pom.xml b/java/flight/flight-sql-jdbc-driver/pom.xml
index 1fd9222be..08e47187f 100644

```
I then built the entire Java tree with the following command:
```
JAVA_HOME=/usr/lib/jvm/java-8-openjdk-arm64 mvn -Dmaven.repo.local=/tmp/arrow/.maven_repo clean install
```
Looking in the local Maven repository, I see the following:
```
root@0a9e22d01fcb:/tmp/arrow/java# ls -l ../.maven_repo/org/apache/arrow/flight-sql-jdbc-driver/14.0.0-SNAPSHOT/

```
This seems pretty workable for most people. Folks using Maven/Gradle/whatever to manage their projects would switch to pulling the un-shaded artifact and its corresponding dependencies. Folks needing the shaded JAR would have to start specifying the `shaded` classifier to get that artifact, instead.
