Chapter 4. Analyzing your projects with the MTR plugin
You can analyze your projects with the MTR plugin by creating a run configuration, running an analysis, and then reviewing and resolving migration issues detected by the MTR plugin.
4.1. Creating a run configuration
You can create a run configuration in the Issue Explorer. A run configuration specifies the project to analyze, migration path, and additional options.
You can create multiple run configurations. Each run configuration must have a unique name.
Prerequisite
- You must import your projects into the Eclipse IDE.
Procedure
-
In the Issue Explorer, click the MTR icon (
) to create a run configuration.
On the Input tab, complete the following fields:
- Select a migration path.
- Beside the Projects field, click Add and select one or more projects.
Beside the Packages field, click Add and select one or more the packages.
NoteSpecifying the packages for analysis reduces the run time. If you do not select any packages, all packages in the project are scanned.
On the Options tab, you can select Generate Report to generate an HTML report. The report is displayed in the Report tab and saved as a file.
Other options are displayed. See About MTR command-line arguments in the CLI Guide for details.
- On the Rules tab, you can select custom rulesets that you have imported or created for the MTR plugin.
