--------------------------------------
Summary: Allow the Maven model cache tto recache a maven model on
request
Key: MNG-6911
URL: https://issues.apache.org/jira/browse/MNG-6911
Project: Maven
Issue Type: Bug
Components: IDEs, POM
Affects Versions: 3.6.3
Environment: Linux (Fedora 30-32)
Reporter: Andrew Obuchowicz
Hi, I'm one of the developers of
[LemMinX-Maven|[https://github.com/eclipse/lemminx-maven]|https://github.com/eclipse/lemminx-maven],]
which is a project that implements the Language Server Protocol for editing
Maven pom.xml files (any LSP client editor can easily gain pom.xml editing
features with this project).
We've encountered an [issue|[https://github.com/eclipse/lemminx-maven/pull/67]]
where modifications to a parent pom (such as adding a new property) are not
reflected in the child pom, as the global model cache has an outdated version
of the parent pom (before the modification was made).
Disabling the global model cache works as a temporary workaround, eg.
{code:java}
System.setProperty(DefaultProjectBuilder.DISABLE_GLOBAL_MODEL_CACHE_SYSTEM_PROPERTY,
Boolean.toString(true));
{code}
However, we'd still like to use the model cache and not have to disable it
entirely.
Thus, it would be beneficial if the model cache could "uncache" (or refresh) a
pom that has been modified. From our project, we can easily detect when a
pom.xml has been modified, thus tracking pom modifications does not need to be
implemented. *What is required on the Maven API side* is to be able to signal
that a pom.xml has been modified, and should be recached with the new
modifications.
Also, I apologize in advance if this was reported under the wrong project or
component. Feel free to place it where it should be.
