Wrong error message when relativePath wrong
-------------------------------------------
Key: MNG-4907
URL: http://jira.codehaus.org/browse/MNG-4907
Project: Maven 2 & 3
Issue Type: Improvement
Components: Inheritance and Interpolation
Affects Versions: 3.0
Environment: maven 3.0, windows XP
Reporter: Marshall Schor
Priority: Minor
Attachments: mvn-parent-relative-path.zip
I'll attach a zipped sample showing the issue; it has 3 folders, each having a
small pom. They are named childFolder, parentFolder, and submodule.
The child has the parent as its parent.
The child has a <modules> section listing the parent and the submodule as
things to be built.
The submodule list "parent" as its parent, but fails (on purpose, to illustrate
the issue) to include a <relativePath> element.
If I do mvn clean on the "submodule", it says, correctly:
[ERROR] The build could not read 1 project -> [Help 1]
[ERROR]
[ERROR] The project t:submodule:1-SNAPSHOT
(D:\mavenAlign\trunk\mvn-parent-relative-path\submodule\pom.xml) has 1 error
[ERROR] Non-resolvable parent POM: Could not find artifact
t:parent:pom:1-SNAPSHOT and 'parent.relativePath' points at wrong local POM @
line 8, column 11 -> [Help 2]
Note: line 8, column 11 is right after the "<parent>" element in the source.
But, if I run mvn clean on the "child", it says, incorrectly:
[ERROR] The build could not read 1 project -> [Help 1]
[ERROR]
[ERROR] The project t:child:1-SNAPSHOT
(D:\mavenAlign\trunk\mvn-parent-relative-path\childFolder\pom.xml) has 1 error
[ERROR] Non-resolvable parent POM: Could not find artifact
t:parent:pom:1-SNAPSHOT and 'parent.relativePath' points at wrong local POM @
line 5, column 11 -> [Help 2]
In fact, the ...\childFolder\pom.xml doesn't have an error, and the message
that it points at the wrong local POM at line 5, column 11 is not correct. If
you comment out the <module> reference in this pom to the "submodule", it works
fine. The error is actually in the submodule. The line 5, column 11 refers to
a spot right after the "<parent>" element in the child module, where everything
is OK.
This of course, misleads the person trying to debug this, to look hard in the
wrong place :-).
