背景
在JetBrains-intellij-idea 插件开发时，出现一个不影响运行，但影响心情的错误提示：
Cannot resolve the latest Gradle IntelliJ Plugin version
org.gradle.api.GradleException: Cannot resolve the latest Gradle IntelliJ Plugin version
使用的gradle版本：8.11
java版本：17
网络条件：国内互联网，访问不了GITHUB

initializeIntelliJPlugin这个task的作用是：初始化Gradle IntelliJ插件并执行各种检查，例如插件是否是最新的。
检查方式是：用插件名查找github仓库是否有更新。
因此：如果你的电脑无法正常访问github，那么插件将无法正确更新。
解决办法：
在build.gradle.kts（如果Groovy的话是build.gradle）文件的tasks下增加如下内容：
initializeIntelliJPlugin {selfUpdateCheck = false
}排查办法
找到这个task对应的源码(如果用的是idea，编译正常的话ctrl加左键点击即可。能点进去的前提是你的gradle能下载gradle-intellij-plugin这个插件，点不进去你就自己在这个插件下搜吧)
// 这里定义了一个task提供者
val TaskContainer.`initializeIntelliJPlugin`: TaskProvider<org.jetbrains.intellij.tasks.InitializeIntelliJPluginTask>get() = named<org.jetbrains.intellij.tasks.InitializeIntelliJPluginTask>("initializeIntelliJPlugin")//查找实现类可以找到这个：
abstract class InitializeIntelliJPluginTask : DefaultTask() {
......private fun checkPluginVersion() {if (!selfUpdateCheck.get() || selfUpdateLockPath.get().exists() || offline.get()) {return}try {val version = getCurrentPluginVersion()?.let(Version::parse).or { Version() }val latestVersion = LatestVersionResolver.fromGitHub(PLUGIN_NAME, GITHUB_REPOSITORY)if (version < Version.parse(latestVersion)) {warn(context, "$PLUGIN_NAME is outdated: $version. Update `$PLUGIN_ID` to: $latestVersion")}selfUpdateLockPath.get().create()} catch (e: Exception) {error(context, e.message.orEmpty(), e)}}
......
}从源码很明显可以看到，他是从github里找这个插件，判定当前版本是不是最新版本。
如果不是最新版，那么会给你一个提示。
解决办法就很简单了：!selfUpdateCheck.get() || selfUpdateLockPath.get().exists() || offline.get()
让他为 true，其中 selfUpdateCheck、offline这两个参数满足一个就行了。一个是检查最新的开关，一个是离线模式。
我给的是关闭更新检查开关。
