# ArtifactCoordinates.getId() produces double colon when classifier is empty
**Found in:** maven-4.0.x branch
**File:**
`api/maven-api-core/src/main/java/org/apache/maven/api/ArtifactCoordinates.java`
(lines ~72-78)
**Severity:** High
## Description
When `getClassifier()` returns an empty string (the standard case),
`getId()` produces a double colon:
```java
default String getId() {
String c = getClassifier();
return getGroupId() + ':' + getArtifactId() + ':' + getExtension()
+ ':' + c // always adds ":" + c, even when empty
+ (c.isEmpty() ? "" : ":")
+ getVersionConstraint();
}
```
This produces `groupId:artifactId:extension::versionConstraint` — a double
colon. Compare with the correct `Artifact.key()` method which correctly
produces `groupId:artifactId:extension:version` when the classifier is empty.
The fix should match the pattern in `Artifact.key()`:
```java
return getGroupId() + ':' + getArtifactId() + ':' + getExtension()
+ (c.isEmpty() ? "" : ":" + c)
+ ':' + getVersionConstraint();
```
