Add jSpecify support in Gradle projects

If you are using Gradle, then add the jspecify dependency. In build.gradle or build.gradle.kts, update or add the following jspecify configuration.

groovy
1plugins {
2    id("net.ltgt.errorprone") version "4.3.0"
3}
4
5tasks.withType(JavaCompile).configureEach {
6    options.errorprone {
7        disableAllChecks = true // Other error prone checks are disabled
8        option("NullAway:OnlyNullMarked", "true") // Enable nullness checks only in null-marked code
9        error("NullAway") // bump checks from warnings (default) to errors
10        option("NullAway:JSpecifyMode", "true") // https://github.com/uber/NullAway/wiki/JSpecify-Support
11    }
12    // Keep a JDK 25 baseline
13    options.release = 25
14}
15
16dependencies {
17    implementation("org.jspecify:jspecify:1.0.0")
18    errorprone("com.google.errorprone:error_prone_core:2.42.0")
19    errorprone("com.uber.nullaway:nullaway:0.12.12")
20}

Add @NullMarked to package-info.java files

In every java package under the application main source code (src/main/java), create package-info.java if not exists already, and add the @NullMarked annotation as follows:

java
1@org.jspecify.annotations.NullMarked
2package com.mycompnay.myproject;

If package-info.java file already exists, update the file to add @org.jspecify.annotations.NullMarked annotation. DO NOT REMOVE ANY OTHER EXISTING CODE IN package-info.java FILE.

Verify jSpecify support

If python is installed, after adding the jSpecify support, run scripts/verify_nullmarked.py to check if all non-empty packages has package-info.java file or not.
