Hi !
I am developing with Java 11 (OpenJDK) and have the following runtime problem
when calling DBUtils.md5Hex()
Exception in thread "Thread-0" java.lang.NoClassDefFoundError:
org/apache/commons/codec/digest/DigestUtils
The purpose of my code is very classical: a history-aware save function, which
only overwrites a file when the content to save differs from the content in the
existing file (see below).
Surprisingly, compilation works fine.
Does apache commons codec support Java 11 ?
Am I doing something wrong ?
Might this be due to a missing dependency ?
Best regards,
François Vandewalle
public boolean save(String target_file_name){
try {
// Check whether the file changed by comparing MD5 hashes
String md5_existing_file = "";
try (InputStream in = new FileInputStream(target_file_name)) {
md5_existing_file = DigestUtils.md5Hex(in);
}
String md5_new_content;
md5_new_content = DigestUtils.md5Hex(file_content);
if (!md5_new_content.equals(md5_existing_file)){
try (BufferedWriter out = new BufferedWriter(new
FileWriter(target_file_name, false))) {
try {
out.write(file_content);
}
catch (IOException ioEx) {
}
}
}
}
catch (IOException ioEx){
}
return true;
}
