Environment
- Operating System: OSX 10.15.4
- JDK version: 1.8
- Visual Studio Code version: 1.44.1
- Java extension version: 0.60
Steps To Reproduce
mvn archetype:generate \
-DarchetypeGroupId=org.apache.flink \
-DarchetypeArtifactId=flink-quickstart-java \
-DarchetypeVersion=1.10.0
Current Result
use vscode open project, No error message. But will fail to build. Only view the error message through the Output panel
when I remove lifecycle-mapping from pom.xml, Extension works good.
Expected Result
At least give an obvious error message. Best to solve this problem.
Contributor guide
First steps
- Read the whole issue, then the project's contributing guide.
- Comment on the issue to say you are picking it up — it saves two people doing the same work.
- Fork the repository and make your change on a branch.
- Open a pull request that references the issue number.
Research direction
Reproduce the issue with the provided mvn archetype:generate command and inspect PackageCommand.getContainers and PackageCommand.getChildren, where the stack trace reports the failure. Compare behavior with and without the lifecycle-mapping plugin; done means the project loads without the Java Model Exception or presents an obvious error instead of failing silently.
