createTempDirectory

public static Path createTempDirectory(Path dir,
 String prefix,
 FileAttribute<?>... attrs)
                                throws IOException

See Files.createTempDirectory(Path, String, FileAttribute[]). This function will create the parent directories if they do not exist.

Throws:

IOException

setReadOnly

public static void setReadOnly(Path path,
 boolean isReadOnly)
                        throws IOException

Sets readonly bit on Path

Throws:

IOException

setExecutable

                          throws IOException

Sets executable bit on Path

Throws:

setAccessibleOnlyByOwner

public static void setAccessibleOnlyByOwner(@NotNull
 @NotNull Path path)
                                     throws IOException

Removes access to Path from non-owners. Note, for NTFS it removes all ACLs except owner. So if owner is not listed at ACLs then Path will become unavailable for Bamboo.

Throws:

resolvePathUnderParent

public static Path resolvePathUnderParent(@NotNull
 @NotNull Path parent,
 @NotNull
 @NotNull String child)

Fulfills the general contract of Path.resolve(String). The returned path is always in normalized and always rooted under the parent argument. Attempts to traverse out of the parent directory will result in IllegalArgumentException being thrown.

Parameters:

parent - parent directory

child - child under parent directory. Relative paths are allowed as long as the result is under the parent directory

Returns:

a canonical child File rooted under parent directory
