build.gradle中的代码如下：

apply from: 'random.gradle'
//def randomFile = rootProject.file('app/random.gradle')
//apply from: randomFile
task getName1{
    doLast{
        def name = generateName3(5)
        println "Romdd------------- $name"
    }
}

static String generateName(int index) {
    return generateName3(index)

}

random.gradle中代码如下：

import java.security.SecureRandom

SecureRandom random = new SecureRandom()

ext.generateName3 = { length ->

    println "阿猫阿狗------------- $name"
    StringBuilder sb = new StringBuilder()
    String alphabets = "abcdefghijklmnopqrstuvwxyz"
    for (int i=0; i<length; i++) {
        int index = random.nextInt(alphabets.length())
        sb.append(alphabets.charAt(index))
    }
    return sb.toString()
}

//// 随机生成一个名称
static String generateName0(int index) {
    def random = new Random()
    def abc = "abcdefghijklmnopqrstuvwxyz".toCharArray()
    def sb = new StringBuilder()
    for (i in 0..4) {
        sb.append(abc[random.nextInt(abc.size())])
    }
    int temp = index
    while (temp >= 0) {
        sb.append(abc[temp % abc.size()])
        temp = temp / abc.size()
        if (temp == 0) {
            temp = -1
        }
    }
    sb.append(index.toString())
    return sb.toString()
}

加日志，看看走到哪步，然后你静态的调用非静态的吗？
