IDEA-383419 Gradle: add support alternativeJrePath RunConfiguration option for gradle-idea-ext

[entrypointkr]

YouTrack: https://youtrack.jetbrains.com/issue/IDEA-383419/IDEA-EXT-Alternative-JRE-Path-in-JarApplication

Releated PR: JetBrains/gradle-idea-ext-plugin#140

Purpose

To support configuring the JRE option for IntelliJ IDEA Run Configurations — JarApplication / Application — via gradle-idea-ext.

Implementation

I opened the PR to make gradle-idea-ext export alternativeJrePath, and implemented the code and tests to read it from each IntelliJ IDEA importer and apply it.

Main changes

• jarApplication:
  • Impl: JarApplicationRunConfigurationImporter
  • Test: GradleSettingsImportingTest#testJarApplicationRunConfigurationSettingsImport
• application:
  • Impl: JavaApplicationRunConfigurationImporter
  • Test: GradleSettingsImportingTest#testApplicationRunConfigurationSettingsImport

I removed deprecated consumeIfCast usage in each importer and updated it to use pattern variables.

Fields related to the JRE path are in:

JvmConfigurationOptions( // com.intellij.execution.JvmConfigurationOptions
  alternativeJrePath: String?,
  isAlternativeJrePathEnabled: Boolean,
)

If the input alternativeJrePath is present and not empty, set (alternativeJrePath, true).
otherwise, set (null, false).
What I want to emphasize here is that it is also set to (null, false) when the value is empty. Would it be a problem that there is no case where it becomes ("", true)?

Also, in each test, I used JavaApplicationRunConfigurationImporter / JarApplicationRunConfigurationImporter instead of TestRunConfigurationImporter to verify that the configuration was applied correctly.

Extra changes

• ApplicationConfiguration:
  • Updated the part that uses the deprecated field MAIN_CLASS_NAME: ApplicationModulePathTest#L111
  • Updated the comment on the deprecated field.
• Fixed an issue that occurs when testing idea-ext from a local repository that has not been published yet: TestGradleBuildScriptBuilder#L92
