maven compile error

Could not get HEAD Ref, are you sure you have some commits in the dotGitDirectory

I'm not sure what you mean. Could you provide the steps for reproducing or any log?

By the way, the following steps work for my local environment.

1. git clone https://github.com/Canner/wren-engine.git
2. cd wren-engine
3. ./mvnw clean install -DskipTests

Thank you! It has worked now. Previously, I downloaded the source code directly, but now I used git clone, and the compilation has passed. However, in the trino-parser module, there's currently an error: "Cannot resolve symbol 'TypeCalculationParser'".

I want to directly debug the project, but when I run wren-server, I encounter configuration file errors. What configurations need to be added to config.properties, and where should this file be placed?

It seems that you use the IntelliJ as the IDE. I think you can run the maven build through IDE directly. (IDE will link them automatically).

mvn clean install -DskipTests

Because some classes of Wren Server are generated by other tools (e.g. anltr4), you need to generate them first.

You need to add the VM options when starting the server. You can put the config on where you want. Just add the path to this option.

-Dconfig=etc.local/config.properties

I provided a minimized config.properties here.

node.environment=test
wren.experimental-enable-dynamic-fields=true

Because most config of wren engine has been deprecated, I believe you can just use the above config to start the Wren Server.
For more additional configs, you can find them on the classes named xxxConfig or ConfigManager.

hope helpful.

Yes, I am using IntelliJ as my IDE. Currently, I have configured the startup parameters in IntelliJ as follows:

io.wren.server.WrenServer -Dconfig=/Users/jianchuanli/mindflow/opensource/wren-engine/config.properties

However, after running it, I am still encountering the following error:

==========

Errors:

Invalid configuration property node.environment: must not be null (for class io.airlift.node.NodeConfig.environment)

I think you put the config at the wrong place. Where you set is the program argument but it should be set at VM options.
You can find the VM option by clicking Modify options. Then, you will get an additional field for VM option

The log that appears indicates success, right?

Exactly
