Question

在正常情况下将正确的字节写入文件，但结合Gradle 2.3 + JUnit 4.11意外结果。

import org.junit.Test;
import java.io.FileOutputStream;
import static org.junit.Assert.*;

public class TestUTF16Test
{
   @Test
   public void testWrite() throws Exception
   {
      try (FileOutputStream bin = new FileOutputStream("testUTF16junit.txt")) {
         bin.write("Русский".getBytes("UTF-16LE"));
      }
   }
}

的build.gradle

apply plugin: 'java'

sourceCompatibility = 1.7
version = '1.0'

repositories {
    mavenCentral()
}

dependencies {
    testCompile group: 'junit', name: 'junit', version: '4.11'
}

$ gradle.bat：clean：test

结果：

20 04 A0 00 21 04 53 04 21 04 03 04 21 04 03 04... 28 bytes

但它应该是：

20 04 43 04 41 04 41 04 3A 04 38 04 39 04 = 14 bytes

Gradle fix

[ compileJava, compileTestJava ]*.options*.encoding = 'UTF-8'

2015，javac无法识别BOM的Unicode！

>javac.exe src\test\java\TestUTF16Test.java
src\test\java\TestUTF16Test.java:1: error: illegal character: '\u00bb'
я╗┐import org.junit.Test;
 ^
1 error

>javac.exe -version
javac 1.8.0_25

现在我理解为什么IDE没有添加BOM ...

Gradle 2.3 + JUnit 4.11 =破碎的Charset
