我正在使用intellij idea 13.0.当我试图从subversion结帐时,我收到错误

Cannot load supported formats: Cannot run program "svn": CreateProcess error=2, The system cannot find the file specified

我该如何解决？

我有加密\解密文件的算法:

    private static byte[] encrypt(byte[] raw, byte[] clear) throws Exception {
    SecretKeySpec skeySpec = new SecretKeySpec(raw, "AES");
    Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding");
    cipher.init(Cipher.ENCRYPT_MODE, skeySpec);
    byte[] encrypted = cipher.doFinal(clear);
    return encrypted;
}


private static byte[] getRawKey(byte[] seed) throws Exception {
    KeyGenerator kgen = KeyGenerator.getInstance("AES");
    SecureRandom sr = new SecureRandom();
    sr.setSeed(seed);
    kgen.init(sr); // 192 and 256 bits may not be available
    SecretKey skey = kgen.generateKey();
    byte[] raw = skey.getEncoded();
    return raw;
}

private static byte[] decrypt(byte[] raw, byte[] encrypted) throws Exception {
    SecretKeySpec …

这是我在Swift的早期版本中可行的代码:

 let imageOptionsDictKeys = [ kCVPixelBufferPixelFormatTypeKey, kCVPixelBufferWidthKey,  kCVPixelBufferHeightKey, kCVPixelBufferOpenGLESCompatibilityKey, kCVPixelBufferIOSurfacePropertiesKey]
 let imageOptionsDictValues = [ cvPixelFormatType,  frameW, frameH, boolYES]

 var keyCallbacks = kCFTypeDictionaryKeyCallBacks
 var valueCallbacks = kCFTypeDictionaryValueCallBacks

 let imageOptions = CFDictionaryCreate(kCFAllocatorDefault, UnsafeMutablePointer(imageOptionsDictKeys), UnsafeMutablePointer(imageOptionsDictValues), 4, &keyCallbacks, &valueCallbacks)

在Swift 3.0中进行更改后,我必须将我的键和值数组转换UnsafeMutablePointer<UnsafeRawPointer?>为创建CFDictionary.

这条路:

    let imageOptionsDictKeysPointer =  UnsafeMutablePointer<UnsafeRawPointer?>.allocate(capacity: 1)
    imageOptionsDictKeysPointer.initialize(to: imageOptionsDictKeys)

出现错误访问错误.

在阅读文档后,我正在尝试编译此代码:

        let imageOptionsDictKeys = [kCVPixelBufferPixelFormatTypeKey, kCVPixelBufferWidthKey,  kCVPixelBufferHeightKey, kCVPixelBufferOpenGLESCompatibilityKey]
        let imageOptionsDictKeysRawPointer = Unmanaged.passUnretained(imageOptionsDictKeys).toOpaque()
        let imageOptionsDictKeysPointer =  UnsafeMutablePointer<UnsafeRawPointer?>.allocate(capacity: 1)
        imageOptionsDictKeysPointer.initialize(to: imageOptionsDictKeysRawPointer)

        let imageOptionsDictValues = [ cvPixelFormatType,  frameW, frameH, boolYES]
        let imageOptionsDictValuesRawPointer = Unmanaged.passUnretained(imageOptionsDictValues).toOpaque()
        let …
