> Hi, all,
> Newbie here trying to figure out how to use published
> beam-sdks-java-extensions-sql-2.9.0 in my own project.
> I tried to create a gradle project to use BeamSQL sdk libraries. Here is the
> build.gradle I have:
> {code:java}
> plugins {
> id 'java'
> }
> group 'com.mycompany.myproject'
> version '1.0-SNAPSHOT'
> sourceCompatibility = 1.8
> repositories {
> mavenCentral()
> }
> apply plugin: 'java'
> sourceSets.main.java.srcDirs = [
> 'src/main/java'
> ]
> dependencies {
> compile 'org.apache.beam:beam-sdks-java-core:2.9.0'
> compile 'org.apache.beam:beam-sdks-java-extensions-sql:2.9.0'
> compile 'com.google.code.findbugs:jsr305:3.0.2'
> runtime 'org.apache.beam:beam-runners-direct-java:2.9.0'
> testCompile group: 'junit', name: 'junit', version: '4.12'

> // Run basic SQL example
> task runBasicExample(type: JavaExec) {
> description = "Run basic SQL example"
> main = "com.mycompany.myproject.streamsql.examples.BeamSQLExample"
> classpath = sourceSets.main.runtimeClasspath
> args = ["--runner=DirectRunner"]
> println classpath.getAsPath()
> println args
> }
> {code}
> The example BeamSQLExample is just copied from
> [https://github.com/apache/beam/blob/master/sdks/java/extensions/sql/src/main/java/org/apache/beam/sdk/extensions/sql/example/BeamSqlExample.java].
> I was able to compile the example in JDK8. However, when I tried to run it, I
> hit the following exception:

> I also have tried to compile the sql sdk libraries in Beam's source repo and
> just copying over the generated class files over to my runtime classpath.
> Apparently, that did not work well since there are many shadowed libraries
> now need explicit declaring dependencies. I tried to search for an example of
> maven or gradle dependency declaration that users will use to create their
> own application using the SQL SDKs but was not lucky enough to find one.
