Unable create maven project with latest theia (windows) IDE

[octopus88888]

Scenario 1: 1) Create Maven Project 2) Select spring-boot-blank-archetype

3) Faced error to create maven project

Scenario 2: Similar error message with command line if provide -DoutputDirectory with invalid path:

mvn archetype:generate -DarchetypeGroupId=com.nokia.dos -DarchetypeArtifactId=mechanism-driver-archetype -DarchetypeVersion=24.1.2 -DoutputDirectory=file:///c%3A/<path>
...
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-archetype-plugin:3.2.1:generate (default-cli) on project standalone-pom: java.io.IOException: The file
name, directory name, or volume label syntax is incorrect -> [Help 1]

Does this only occur with the Spring Boot archetype or with all templates?

[msujew]

Since the task tries to execute the -DoutputDirectory=file:///c%3A/ argument, I assume there's something wrong with out URI decoding/encoding in this part of the API.

not only occur with the Spring Boot archetype, tried others also get the same error.

[sgraband]

I can take a look!

[tsmaeder]

Doesn't this sound like a problem in https://github.com/eclipse-jdtls/eclipse.jdt.ls ?

[msujew]

@tsmaeder I haven't confirmed this bug in vscode yet (I don't do Java coding these days), but I assume it works as expected there. In that case it's probably related to Theia in some way or another.

[sgraband]

I just checked. The extension (and command) works in VSCode. So i would assume, that the API that the extension uses does not behave the same in Theia. Probably due to the file path decoding/encoding.

[sgraband]

I found where this issue comes from, but i am unsure on how to deal with it:

The extension provides the args for the call like this:

    "org.apache.maven.plugins:maven-archetype-plugin:3.1.2:generate",
    `-DarchetypeArtifactId="${archetypeArtifactId}"`,
    `-DarchetypeGroupId="${archetypeGroupId}"`,
    `-DarchetypeVersion="${archetypeVersion}"`,
    `-DgroupId="${groupId}"`,
    `-DartifactId="${artifactId}"`

Note, that the values for the parameters are wrapped in ".

This is how the commandLine value looks for the task on the backend then:

cmd.exe /S /C ""mvn org.apache.maven.plugins:maven-archetype-plugin:3.1.2:generate -DarchetypeArtifactId="spring-boot-blank-archetype" -DarchetypeGroupId="am.ik.archetype" -DarchetypeVersion="1.0.6" -DgroupId="com.example" -DartifactId="demo"""

We use the commandLine value for tasks on windows.

When i try to run that commandLine statement i get the following error message:

The syntax of the command is incorrect.

As far as i know the /S argument should remove the first and last " of a command. So i would expect the following command to work, but for some reason it doesn't (same command as above without duplicate "):

cmd.exe /S /C "mvn org.apache.maven.plugins:maven-archetype-plugin:3.1.2:generate -DarchetypeArtifactId="spring-boot-blank-archetype" -DarchetypeGroupId="am.ik.archetype" -DarchetypeVersion="1.0.6" -DgroupId="com.example" -DartifactId="demo""

After some testing in the commandline i came to the conclusion that the command works when you either remove the wrapping set of ":

cmd.exe /S /C mvn org.apache.maven.plugins:maven-archetype-plugin:3.1.2:generate -DarchetypeArtifactId="spring-boot-blank-archetype" -DarchetypeGroupId="am.ik.archetype" -DarchetypeVersion="1.0.6" -DgroupId="com.example" -DartifactId="demo"

(This also works without the /S argument)

Or if you remove the " around the arguments.

cmd.exe /S /C "mvn org.apache.maven.plugins:maven-archetype-plugin:3.1.2:generate -DarchetypeArtifactId=spring-boot-blank-archetype -DarchetypeGroupId=am.ik.archetype -DarchetypeVersion=1.0.6 -DgroupId=com.example -DartifactId=demo"

I am unsure on how we should tackle that issue, because other commands will likely need the wrapping " for them to work correctly, right? Any ideas @tsmaeder or @msujew ?

Just as a note: During debugging i also found that this.workspaceService.workspace?.resource.toString(); in the getContext() function of task-service.ts returns file:///c%3A/<path> on Windows. It seems to not cause any problems with this extension, but it does not seem correct, does it?

[tsmaeder]

@sgraband why would file:///c%3A/<path> not be the correct url? Looks like the url-encoded form of c:/<path> to me.

[tsmaeder]

@sgraband can you give more context on "how the extension provides the args for the call"? Is this a json file, an API call?

[msujew]

@sgraband I'm not sure whether the file URI is correct or not. It might need to return uri.path.fsPath instead. However, we should take a look at what vscode provides there.

[sgraband]

@sgraband why would file:///c%3A/ not be the correct url? Looks like the url-encoded form of c:/ to me.

@tsmaeder might be, like i said it did not have any impact on executing the task, but i am unsure on what is expected there. I looked at this due to the comment and Issue description above that indicated it might have something to do with this. However like @msujew suggested i can take a look on what vscode provides there.

I took a look at this function. I mainly debugged the commandLine values from above at this line.

[tsmaeder]

@sgraband the last url is broken.

[sgraband]

Sorry about that: https://github.com/eclipse-theia/theia/blob/3e7f6eec297c4029ef01b2ef2c8f20361360c48c/packages/task/src/node/process/process-task-runner.ts#L88 (also fixed it above)

[sgraband]

@tsmaeder did you already have time to take a look and/or have an idea on how we could tackle this issue? I would have time this month to provide a fix, but like indicated in my earlier comment i am missing an idea on how to solve this issue.

[tsmaeder]

No, sorry, @sgraband I have no idea what the right thing to do is, here. In general, it's a good idea to keep things as objects instead of encoding them into a string for as long as possible, but not sure how that applies to this problem.
