Project scenario:
Ruoyi framework requires back-end deployment and packaging
Problem Description
For example: mac use command
mvn clean package -Dmaven.test.skip=true
The error is reported as follows
zsh: command not found: mvn
Cause Analysis:
The "zsh: command not found: mvn" error message indicates that the "mvn" command is not found on your system, which means that Maven is not installed correctly or is not in the system's PATH environment variable.
solution:
To resolve this issue, you can follow these steps:
1. Install Maven:
If you don't have Maven installed yet, you first need to install it. You can use a package manager such as Homebrew (on macOS), apt (on Ubuntu) or download and install Maven manually.
On macOS, you can use Homebrew to install Maven:
brew install maven
On Ubuntu, you can install Maven using apt:
sudo apt-get update
sudo apt-get install maven
Manually download and install Maven: You can download the Maven binary distribution package from the Maven official website (https://maven.apache.org/download.cgi), and then install it according to the instructions in the official documentation.
2. Confirm whether the installation is successful:
After the installation is complete, open a terminal and run the following command to confirm whether Maven was installed successfully:
mvn -version
If Maven is installed successfully, Maven version information will be displayed.
There is another bug
Matching Java Virtual Machines (5):
18.0.2.1 (x86_64) “Oracle Corporation” - “Java SE 18.0.2.1” /Library/Java/JavaVirtualMachines/jdk-18.0.2.1.jdk/Contents/Home
17.0.1 (x86_64) “Oracle Corporation” - “Java SE 17.0.1” /Library/Java/JavaVirtualMachines/jdk-17.0.1.jdk/Contents/Home
1.8.321.07 (x86_64) “Oracle Corporation” - “Java” /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home
1.8.0_321 (x86_64) “Oracle Corporation” - “Java SE 8” /Library/Java/JavaVirtualMachines/jdk1.8.0_321.jdk/Contents/Home
1.8.0_241 (x86_64) “Oracle Corporation” - “Java SE 8” /Library/Java/JavaVirtualMachines/jdk1.8.0_241.jdk/Contents/Home
/Library/Java/JavaVirtualMachines/jdk-18.0.2.1.jdk/Contents/Home
There are multiple versions of Java Virtual Machines (JVMs) installed on your system. Maven may get confused because it doesn't know which Java version to use.
First, make sure that the environment variables in the terminal you are using are set to the version of Java you want to use. If you want to use Java 18.0.2.1, you can set the following environment variables:
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-18.0.2.1.jdk/Contents/Home
export PATH=$JAVA_HOME/bin:$PATH
Make sure to add these commands to your shell configuration file (such as ~/.zshrc or ~/.bashrc) and make them effective by running the source command.
You can then run mvn -versionthe command again to ensure that Maven is using the Java version of your choice.
Finally return to the topic
and use it again
mvn clean package -Dmaven.test.skip=true
You can pack it out normally.
