Method Detail

close

public static void close(java.lang.Object stream)

getPack200Commands

@Deprecated
public static java.lang.String[] getPack200Commands(java.lang.String cmd)

Deprecated. See bug and issue for details.

Get the set of commands to try to execute pack/unpack

Parameters:

cmd - the command, either "pack200" or "unpack200"

Returns:

null as pack200 is not supported on Java >= 14

transferStreams

public static void transferStreams(java.io.InputStream source,
                                   java.io.OutputStream destination,
                                   boolean close)
                            throws java.io.IOException

Transfers all available bytes from the given input stream to the given output stream. Closes both streams if close == true, regardless of failure. Flushes the destination stream if close == false

Parameters:

source -

destination -

close -

Throws:

java.io.IOException

clear

public static boolean clear(java.io.File root)

Deletes all the files and directories from the given root down (inclusive). Returns false if we could not delete some file or an exception occurred at any point in the deletion. Even if an exception occurs, a best effort is made to continue deleting.

clearChildren

public static boolean clearChildren(java.io.File root)

Deletes all the files and directories from the given root down, except for the root itself. Returns false if we could not delete some file or an exception occurred at any point in the deletion. Even if an exception occurs, a best effort is made to continue deleting.

getPackExclusions

@Deprecated
public static java.util.Set<java.lang.String> getPackExclusions(java.util.Properties properties)

Deprecated. See bug for details.

getSignExclusions

public static java.util.Set<java.lang.String> getSignExclusions(java.util.Properties properties)

concat

public static java.lang.String concat(java.lang.String[] array)

toStringArray

public static java.lang.String[] toStringArray(java.lang.String input,
                                               java.lang.String separator)

getEclipseInf

public static java.util.Properties getEclipseInf(java.io.File jarFile,
                                                 boolean verbose)

Get the properties from the eclipse.inf file from the given jar. If the file is not a jar, null is returned. If the file is a jar, but does not contain an eclipse.inf file, an empty Properties object is returned.

Parameters:

jarFile -

Returns:

The eclipse.inf properties for the given jar file

shouldSkipJar

public static boolean shouldSkipJar(java.io.File input,
                                    boolean processAll,
                                    boolean verbose)

storeProperties

public static void storeProperties(java.util.Properties props,
                                   java.io.OutputStream stream)

Stores the given properties in the output stream. We store the properties in sorted order so that the signing hash doesn't change if the properties didn't change.

Parameters:

props -

stream -
