我正在尝试使用以下命令从shell读取输出数据
def cmd = "adb shell echo \$EXTERNAL_STORAGE"
def proc = cmd.execute()
println proc.in.text
当我只是在groovy脚本中尝试该代码时，结果就没什么好用的了。
最终我发现问题应该是新的String(bytes)，下面的代码在groovy脚本中起作用，而在gradle中不起作用。
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)
谁能告诉我发生了什么事？真烦人...
-----------更新-------------------
我通过@JBirdVegas尝试了代码，这似乎是由Android Studio 2.2.3版稳定引起的。我也试过
IntelliJ IDEA 2016.3.3

还是和以前一样
与命令行中的输出不同，在这些IDE的gradle面板中触发gradle任务时，:
如果选择UTF_8，US_ASCII或ISO_8859_1的字符集，则将看不到任何内容。
最佳答案
似乎对我有用，但我怀疑Charset存在问题。
在Mac上使用模拟器，我看到以下内容
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)}"
}
