Bug: Installing `22.0.2-gradle` first, followed by installing `maven` and `gradle`, will fail

Bug report

• Installing 22.0.2-gradle first, followed by installing maven and gradle, will fail.

To reproduce

• Execute the following command in the new WSL instance of Ubuntu 24.04:

sudo apt update && sudo apt upgrade --assume-yes
sudo apt install unzip zip --assume-yes
curl -s "https://get.sdkman.io" | bash
source "$HOME/.sdkman/bin/sdkman-init.sh"
sdk install java 21.0.9-ms
sdk install java 22.0.2-graalce
sdk use java 22.0.2-graalce
sudo apt-get install build-essential zlib1g-dev --assume-yes
sdk install maven 3.9.12
sdk install gradle 9.2.1
java -version
native-image --version
mvn --version
gradle --version

• This will result in the following error log.

lingh@DESKTOP-74D7840:~$ mvn --version
Command 'mvn' not found, but can be installed with:
sudo apt install maven
lingh@DESKTOP-74D7840:~$ gradle --version
Command 'gradle' not found, but can be installed with:
sudo apt install gradle

Hi, have you tried opening a new terminal? Sometimes we see such issues after first installation of a new candidate.

Hi, have you tried opening a new terminal? Sometimes we see such issues after first installation of a new candidate.

Opening a new terminal is ineffective

• I would say this is useless; mvn and gradle still cannot detect it.

sudo apt update && sudo apt upgrade --assume-yes
sudo apt install unzip zip --assume-yes
curl -s "https://get.sdkman.io" | bash
source "$HOME/.sdkman/bin/sdkman-init.sh"
sdk install java 21.0.9-ms
sdk install java 22.0.2-graalce
sdk use java 22.0.2-graalce
sudo apt-get install build-essential zlib1g-dev --assume-yes
sdk install maven 3.9.12
sdk install gradle 9.2.1
java -version
native-image --version
mvn --version
gradle --version
# Open a new shell terminal in Ubuntu 24.04
mvn --version
gradle --version

• 

lingh@DESKTOP-74D7840:~$ mvn --version
Command 'mvn' not found, but can be installed with:
sudo apt install maven
lingh@DESKTOP-74D7840:~$ gradle --version
Command 'gradle' not found, but can be installed with:
sudo snap install gradle  # version 8.14.3, or
sudo apt  install gradle  # version 4.4.1-20
See 'snap info gradle' for additional versions.

• My discovery is that to temporarily fix this problem, I need to first uninstall sdk uninstall maven 3.9.12 and sdk uninstall gradle 9.2.1, and finally reinstall sdk install maven 3.9.12 and sdk install gradle 9.2.1.

An additional strange discovery

• But there's another strange discovery. To reproduce this bug, I must first install two or more JDKs, then install maven and gradle. Once I install the first JDK, and then install maven and gradle first, followed by multiple JDKs, the problem disappears. For example, the following operation will not have this problem.

sudo apt update && sudo apt upgrade --assume-yes
sudo apt install unzip zip --assume-yes
curl -s "https://get.sdkman.io" | bash
source "$HOME/.sdkman/bin/sdkman-init.sh"
sdk install java 25.0.1-graalce
sdk install maven
sdk install gradle
sdk install java 24.0.2-graalce
sdk install java 22.0.2-graalce
sdk use java 24.0.2-graalce
sdk default java 24.0.2-graalce
sudo apt-get install build-essential zlib1g-dev --assume-yes
sdk version
java -version
native-image --version
mvn --version
gradle --version
