Method Detail

containsNativeCode

public static boolean containsNativeCode(java.nio.file.Path jar)

Heuristically try to determine whether given JAR (or WAR, EAR, ...) file contains native (architecture-dependent) code.

Currently this code only checks only for ELF binaries, but that behavior can change in future.

Returns:

true if native code was found inside given JAR

usesNativeCode

public static boolean usesNativeCode(java.nio.file.Path jar)

Heuristically try to determine whether given JAR (or WAR, EAR, ...) file is using native (architecture-dependent) code.

Currently this code only checks if any class file declares Java native methods, but that behavior can change in future.

Returns:

true given JAR as found inside to use native code

injectManifest

public static void injectManifest(java.nio.file.Path targetJar,
                                  Artifact artifact)

Inject artifact coordinates into manifest of specified JAR (or WAR, EAR, ...) file. The file is modified in-place.

Parameters:

targetJar -

artifact -
