Gradle和包括图像

Question

除了图像之外，当我运行gradle时，一切都很好。我不知道我在哪里做错了......

apply plugin: 'java'

repositories {
mavenCentral()
}

sourceSets {
  main {
    resources {
      srcDirs = ["src/main/java"]
      includes = ["**/*.png"]
includes = ["**/*.css"]
}
}
}

dependencies {
 compile group: 'org.json', name: 'json', version: '20180130'
 }

task(run, dependsOn: 'classes', type: JavaExec) {
   main = 'Main'
   classpath = sourceSets.main.runtimeClasspath
 }
