新的字符串（字節）將不會在gradle這個

Question

我試圖讀取外殼的輸出數據使用

def cmd = "adb shell echo \$EXTERNAL_STORAGE" 
def proc = cmd.execute() 
println proc.in.text 

工作，它竟然是在沒有任何的gradle而我在Groovy腳本只是試過代碼， 有效。

終於我發現問題應該是新的字符串（字節），下面的代碼在groovy腳本中工作，但不在gradle中。

byte[] bytes = [47, 115, 116, 111, 114, 97, 103, 101, 47, 101, 109, 117, 108, 97, 116, 101, 100, 47, 108, 101, 103, 97, 99, 121, 13, 10] 
println new String(bytes) 

任何人都可以告訴我發生了什麼事？真討厭......

-----------更新-------------------

我通過@試過代碼JBirdVegas，它似乎是由Android Studio 2.2.3版穩定引起的。我也試過

IntelliJ IDEA 2016.3.3

和以前一樣。

不像在命令行輸出，當你觸發這些IDE的gradle這個面板的gradle這個任務：

如果選擇UTF_8，US_ASCII或ISO_8859_1的字符集，你會看到什麼。

Answer 1

好吧，我終於發現，這些字節包含了「\ r」（13），當打印到控制檯，的內容整條線被清除，所以什麼也看不到。

Answer 2

似乎正在爲我工​​作，但我懷疑這是Charset的問題。

使用我的Mac模擬器我看到了以下

tasks.create('testAdb') { 
    def cmd = "adb shell echo \$EXTERNAL_STORAGE" 
    def proc = cmd.execute() 
    print "cmd result: $proc.in.text" 
    byte[] bytes = [47, 115, 116, 111, 114, 97, 103, 101, 47, 101, 109, 117, 108, 97, 116, 101, 100, 47, 108, 101, 103, 97, 99, 121, 13, 10] 
    print "new String bytes (with default charset): ${new String(bytes, Charset.defaultCharset())}" 
    println "default charset: ${Charset.defaultCharset()}" 
    print "new String bytes: ${new String(bytes)}" 
    print "new String bytes (with UTF-8 charset): ${new String(bytes, StandardCharsets.UTF_8)}" 
    println "new String bytes (with UTF-16 charset): ${new String(bytes, StandardCharsets.UTF_16)}" 
    println "new String bytes (with UTF-16BE charset): ${new String(bytes, StandardCharsets.UTF_16BE)}" 
    println "new String bytes (with UTF-16LE charset): ${new String(bytes, StandardCharsets.UTF_16LE)}" 
    print "new String bytes (with US_ASCII charset): ${new String(bytes, StandardCharsets.US_ASCII)}" 
    print "new String bytes (with ISO_8859_1 charset): ${new String(bytes, StandardCharsets.ISO_8859_1)}" 
}
