Description
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:
~/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
Where line 56 of my build.gradle file is the split command in the execute task:
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 }
Running with an empty exec.args fixes the issue:
~/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
