如何在测试中使用gradle特性变量依赖？

ext {
    testVersion = '1.0.0'
}

dependencies {
    testImplementation "com.example:test-library:${testVersion}"
}

import org.junit.Test;
import static org.junit.Assert.assertEquals;

public class MyTest {
    @Test
    public void testLibraryVersion() {
        String expectedVersion = "1.0.0";
        String actualVersion = com.example.TestLibrary.getVersion();
        assertEquals(expectedVersion, actualVersion);
    }
}
