I recently had to re-install my laptop and noticed that my IDE stop giving me the hints I was used to get regarding secure code tips.

I’m putting the short setup here so, I can always recall it whenever I have to go over the process again in the future.

First of all I use both a mix of command line and graphical tools. This means that at the CLI level I have installed:

  • maven
  • openjdk

Usually I just rely on the linux packages from the distribution. While maven usually just works as vert.x builds are not that fancy, sometimes I need to switch JDKs. To switch JDK I’ve this simple bash script in my .bashrc:

export JVM_PATH=${PATH}
_comp_jvm () {
    # Get list of directories
    # $2 is the word being completed
    COMPREPLY=($(compgen -d "${HOME}"/.jdks/"$2"))
    # Reduce to basenames
complete -F _comp_jvm jvm
jvm () {
    # Set the path to use the choosen JVM by default
    export PATH="${HOME}"/.jdks/"$1"/bin:${JVM_PATH}
    # Set JAVA_HOME
    export JAVA_HOME="${HOME}"/.jdks/"$1"
    java -version

This will allow me to switch from JVM at the CLI cycling any JDKs installed in ~/.jdks. This is usually the location IntelliJ Idea will download JDKs, so I don’t rely on any other tools. The _comp_jvm function just allows me to list the available JDKs using Tab completion.

For graphical development I’m using IntelliJ Idea. There are a couple of features I enable. Once you open a vert.x module you can enable null checks for vert.x code by:

  1. Go to settings
  2. Build, Execution, Deployment
  3. Compiler
  4. Nullable Annotations
  5. + (add)
  6. io.vertx.codegen.annotations.Nullable

IntelliJ Idea

After this we can add the SpotBugs plugin to give you extra hints of potential bugs in your code:

SpotBugs Plugin

While IDEA will already give you good hints on your code, I’m more interested on a sub-plugin, so you need to:

  1. Go to settings
  2. Tools
  3. SpotBugs
  4. + (add)
  5. find-sec-bugs

SpotBugs Plugin

This will allow us to run extra checks related to security.

That’s it for now!

Happy coding!
