Error: Could not find or load main class com.install4j.runtime.launcher.UnixLauncher
I am receiving an error message: “ Error: Could not find or load main class com.install4j.runtime.launcher.UnixLauncher”.
Here is some information about my environment:
OS: Ubuntu 22.04.3 LTS
Kernel: 6.2.0-1009-aws
CPU: 2
RAM: 8Gb
Architecture: x86_64
Java: openjdk version “1.8.0_382”
OpenJDK Runtime Environment (build 1.8.0_382-8u382-ga-1~22.04.1-b05)
OpenJDK 64-Bit Server VM (build 25.382-b05, mixed mode)
Nexus: 3.61.0-02 (also tried 3.59.0-01)
Steps to reproduce:
sudo apt update -y && sudo apt upgrade -y sudo apt install openjdk-8-jre-headless -y #(Also tried openjdk-8-jdk) sudo mkdir /opt/nexus sudo useradd -d /opt/nexus -s /bin/bash nexus sudo passwd nexus sudo tee /etc/security/limits.d/nexus.conf <<EOF nexus - nofile 65536 EOF curl -L -O https://download.sonatype.com/nexus/3/latest-unix.tar.gz tar -xzf latest-unix.tar.gz sudo mv nexus*/* /opt/nexus sudo mv sonatype-work /opt/ sudo chown -R nexus:nexus /opt/nexus /opt/sonatype-work sudo sed -i ‘s/#run_as_user=“”/run_as_user=“nexus”/g’ /opt/nexus/bin/nexus.rc #I haven’t changed the memory configuration, because it’s a temporary VM, after successful #installation I will install it on the production VM. sudo tee /etc/systemd/system/nexus.service <<EOF [Unit] Description=nexus service After=network.target [Service] Type=forking LimitNOFILE=65536 ExecStart=/opt/nexus/bin/nexus start ExecStop=/opt/nexus/bin/nexus stop User=nexus Restart=on-abort TimeoutSec=600 [Install] WantedBy=multi-user.target EOF sudo systemctl daemon-reload sudo systemctl enable nexus.service --now
I have searched for solutions online, but have not been able to find a resolution to this issue. Could you please guide how to resolve this error and successfully install Nexus Repository 3 on my environment?
Not sure if this will help:
The class file com.install4j.runtime.launcher.UnixLauncher is contained in the jar file ‘[nexus-installation].install4j/i4jruntime.jar’.
The folder starts with a dot ‘.’ - this means the folder is hidden.
Does the jar file exist in your filesystem and are the permissions correct?
‘chown’ with ‘-R’ should honor the hidden folder ‘.install4j’ but I am not quite sure about ‘mv’ (sudo mv nexus*/* /opt/nexus).
Thank you, the issue was with mv command.
