Direção de pesquisa

Start by tracing the Maven project import flow in the vscode-java extension and how it detects duplicate groupId/artifactId values; the issue does not name files or tests. Check how import identity is formed and whether the existing maven.explorer.projectName setting participates. Done when the two sample projects with versions 1.0 and 2.0 can both be imported without duplicate errors.

The Problem

On importing Java projects we get errors like this:

23 Maven project(s) could not be imported due to duplicate groupId/artifactId. See the language server log for details.

We are using a multi-root workspace:

  • Each root folder imports a Java multi-project project from a seperate git local repo.
  • Each repo / folder is a set to a different release branch from the same git repo.

This means that each root folder contains substantially the same set of maven projects, with the same groupId(s) and artifactId(s), but with different version(s).

i.e. as indicated by the error, groupId + artifactId is duplicate / ambiguous,
but the combination groupId + artifactId + version is unique.
For our maven projects the property name is also unique.

Proposed Solution

It should be possible to configure which maven properties are used to import maven projects:
e.g. groupId + artifactId + version
or groupId + artifactId + name

Note the Eclipse IDE when properly configured supports our project structure. Eclipse is able make otherwise duplicate maven projects unique on import via the "Import Maven Projects / Advanced / Name Template" option.

Describe alternatives you've considered

We have seen the setting "maven.explorer.projectName": "${project.groupId}.${project.artifactId}-${project.version}", but that has no effect on project import.

How to Reproduce

The issue can be demonstrated with:

A trusted multi-root-workspace "foo" with two folders foo_one and foo_two imported:

workspace "foo"
├─foo_one
│ └── demo
│     └── pom.xml
└─foo_two
  └── demo
      └── pom.xml

foo_one is a maven project with this pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>foo.bar</groupId>
    <artifactId>demo</artifactId>
    <version>1.0</version>

    <properties>
        <maven.compiler.source>25</maven.compiler.source>
        <maven.compiler.target>25</maven.compiler.target>
    </properties>
</project>

foo_two is a maven project with this pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>foo.bar</groupId>
    <artifactId>demo</artifactId>
    <version>2.0</version>

    <properties>
        <maven.compiler.source>25</maven.compiler.source>
        <maven.compiler.target>25</maven.compiler.target>
    </properties>
</project>

The projects differ only in the version (1.0) vs (2.0)
