> Java quickstart using Gradle doesn't work
> -----------------------------------------
>
> Key: BEAM-10661
> URL: https://issues.apache.org/jira/browse/BEAM-10661
> Project: Beam
> Issue Type: Bug
> Components: website
> Reporter: Marcus Truscello
> Priority: P3
> Labels: documentation, quickstart
> Time Spent: 20m
> Remaining Estimate: 0h
>
> As written, the Java quickstart using Gradle doesn't work. The issue is that
> the {{execute}} task created in step 2 makes it so that the {{exec.args}}
> define is required for every task (including build!), otherwise a
> NullPointerException is thrown.
>
> Example output:
>
> {code:java}
> ~/word-count-beam$ gradle build
> FAILURE: Build failed with an exception.
> * Where:
> Build file '/Users/username/word-count-beam/build.gradle' line: 56
> * What went wrong:
> A problem occurred evaluating root project 'word-count-beam'.
> > java.lang.NullPointerException (no error message)
> * Try:
> Run with --stacktrace option to get the stack trace. Run with --info or
> --debug option to get more log output. Run with --scan to get full insights.
> * Get more help at https://help.gradle.org
> BUILD FAILED in 582ms
> {code}
>
> Where line 56 of my build.gradle file is the split command in the execute
> task:
> {code:java}
> 52 task execute (type:JavaExec) {
> 53 main = System.getProperty("mainClass")
> 54 classpath = sourceSets.main.runtimeClasspath
> 55 systemProperties System.getProperties()
> 56 args System.getProperty("exec.args").split()
> 57 }
> {code}
>
> Running with an empty exec.args fixes the issue:
> {code:java}
> ~/word-count-beam$ gradle build -Dexec.args=""
> Deprecated Gradle features were used in this build, making it incompatible
> with Gradle 7.0.
> Use '--warning-mode all' to show the individual deprecation warnings.
> See
> https://docs.gradle.org/6.5.1/userguide/command_line_interface.html#sec:command_line_warnings
> BUILD SUCCESSFUL in 782ms
> 4 actionable tasks: 4 up-to-date
> {code}
