开发常见问题解答

EDT 与 ReadAction 问题​

在ReadAction下的同步执行：/usr/local/bin/git -c credential.helper= -c core

解决方案示例如下：

/**
 * 参考[com.intellij.execution.process.OSProcessHandler.checkEdtAndReadAction]，我们应该采用这种方式处理，
 * 另一个示例可查看[git4idea.GitPushUtil.findOrPushRemoteBranch]
 */
val future = CompletableFuture<List<GitCommit>>()
val task = object : Task.Backgroundable(project, "xx", false) {
    override fun run(indicator: ProgressIndicator) {
        // 长时间操作
        future.complete(/* 提交列表 */)
    }
}

ProgressManager.getInstance()
    .runProcessWithProgressAsynchronously(task, BackgroundableProcessIndicator(task))

runBlockingCancellable {
    val commits = future.await()
    // 后续处理
}

java.lang.Throwable: 必须在进度指示器下执行：com.intellij.openapi.progress.EmptyProgressIndicator@6c3fd0d8，但当前进程运行在空指示器下。请参考示例：ProgressManager.runProcess()​

 val future = CompletableFuture<String>()
val task = object : Task.Backgroundable(project, "加载中", false) {
    override fun run(indicator: ProgressIndicator) {
        // collectApis 指向你的长时间操作
        future.complete(this.collectApis(project, endpointsProviderList))
    }
}

ProgressManager.getInstance()
    .runProcessWithProgressAsynchronously(task, BackgroundableProcessIndicator(task))

return future.get()
