警告

Eclipse模式插件已经过时，并且与最近的IDEA 12+版本不兼容。如果你安装它，IDE将挂起每一个文件更改，并将响应极慢。

IntelliJ IDEA不使用自动构建，它在运行中检测错误，而不是通过编译器。类似于Eclipse模式将在IDEA 12中可用:

使用Build | Make，它调用增量的Make过程，只编译更改的和依赖的文件(它非常快)。

还有一个常见问题解答条目可能会有所帮助。

Update on the automatic make feature: When run/debug configuration is running, Make project automatically has no effect. Classes on disk will change only on Build | Make. It's the core design decision as in our opinion class changes on disk should be always under user's control. Automatic make is not the copycat of Eclipse feature, it works differently and it's main purpose is to save time waiting for the classes to be ready when they are really needed (before running the app or tests). Automatic make doesn't replace the explicit compilation that you still need to trigger like in the case described in this question. If you are looking for different behavior, EclipseMode plug-in linked in the FAQ above would be a better choice.

您可以按ctrl+s键映射保存和编译在一个步骤。转到键映射设置并搜索Compile。

对于那些使用新的Intellij版本却找不到compiler. autommake .allow.when.app.running的人

https://youtrack.jetbrains.com/issue/IDEA-274903

基本上选项现在已经移动到设置->高级设置->编译器(检查允许自动生成选项)

我最终录制了一个宏来保存并在一步中编译，并按Ctrl+s键映射到它。

使用Reformat and Compile插件(灵感来自Alexandre DuBreuil的Save Actions插件):

目前我只提供了一个jar文件，但这是代码中最重要的部分:

private final static Set<Document> documentsToProcess = new HashSet<Document>();
private static VirtualFile[] fileToCompile = VirtualFile.EMPTY_ARRAY;

// The plugin extends FileDocumentManagerAdapter.
// beforeDocumentSaving calls reformatAndCompile
private static void reformatAndCompile(
        @NotNull final Project project,
        @NotNull final Document document,
        @NotNull final PsiFile psiFile) {
    documentsToProcess.add(document);
    if (storage.isEnabled(Action.compileFile) && isDocumentActive(project, document)) {
        fileToCompile = isFileCompilable(project, psiFile.getVirtualFile());
    }
    ApplicationManager.getApplication().invokeLater(new Runnable() {
        @Override
        public void run() {
            if (documentsToProcess.contains(document)) {
                documentsToProcess.remove(document);
                if (storage.isEnabled(Action.optimizeImports)
                        || storage.isEnabled(Action.reformatCode)) {
                    CommandProcessor.getInstance().runUndoTransparentAction(new Runnable() {
