The proper way that actually works   URL resource   YourClass class getResource  abc    Paths get resource toURI    toFile      It doesn t matter now where the file in the classpath physically is  it will be found as long as the resource is actually a file and not a JAR entry    The seemingly obvious new File resource getPath    doesn t work for all paths  The path is still URL-encoded

Create the classLoader instance of the class you need  then you can access the files or resources easily  now you access path using getPath   method of that class      ClassLoader classLoader   getClass   getClassLoader     String path    classLoader getResource  chromedriver exe   getPath     System out println path

There are two problems on our way to the absolute path     The placement found will be not where the source files lie  but where the class is saved  And the resource folder almost surely will lie somewhere in  the source folder of the project  The same functions for retrieving the resource work differently if the class runs in a plugin or in a package directly in the workspace    The following code will give us all useful paths       URL localPackage   this getClass   getResource          URL urlLoader   YourClassName class getProtectionDomain   getCodeSource   getLocation        String localDir   localPackage getPath        String loaderDir   urlLoader getPath        System out printf  loaderDir    s n localDir    s n   loaderDir  localDir     Here both functions that can be used for localization of the resource folder are researched  As for class  it can be got in either way  statically or dynamically     If the project is not in the plugin  the code if run in JUnit  will print   loaderDir    C     ws source dir target test-classes   localDir    C     ws source dir target test-classes package    So  to get to src rest resources we should go up and down the file tree  Both methods can be used  Notice  we can t use getResource resourceFolderName   for that folder is not in the target folder  Nobody puts resources in the created folders  I hope     If the class is in the package that is in the plugin  the output of the same test will be   loaderDir    C     ws plugin bin   localDir    C     ws plugin bin package    So  again we should go up and down the folder tree      The most interesting is the case when the package is launched in the plugin  As JUnit plugin test  for our example  The output is   loaderDir    C     ws plugin   localDir    package    Here we can get the absolute path only combining the results of both functions  And it is not enough  Between them we should put the local path of the place where the classes packages are  relatively to the plugin folder  Probably  you will have to insert something as src or src test resource here   You can insert the code into yours and see the paths that you have

You can use ClassLoader getResource method to get the correct resource   URL res   getClass   getClassLoader   getResource  abc txt    File file   Paths get res toURI    toFile    String absolutePath   file getAbsolutePath      OR  Although this may not work all the time  a simpler solution -  You can create a File object and use getAbsolutePath method   File file   new File  resources abc txt    String absolutePath   file getAbsolutePath
