|View integration test report (Maven)
||View the integration test report file, if it exists at the
/target/site/failsafe-report.html default location.
|View unit test report (Maven)
||View the unit test report file, if it exists at the
/target/site/surefire-report.html default location.
|View test report (Gradle)
||Open the test report file, if it exists at the

|This property allows a user to define their LemMinX language server runtime without altering the
JAVA_HOME environment variable.
The following settings, which are provided by external extensions, are honoured when you run dev mode commands.
|Maven commands executed by dev mode will honour this setting. When this value is empty, it tries to use
mvnw according to the value of
|Maven for Java extension
|Maven commands executed by dev mode will honour this setting. If true, it tries to use
mvnw if a Maven wrapper file can be found. Otherwise it will use
