IntelliJ IDEA tells me "Error:java: Compilation failed: internal java compiler error idea"
提问by ieatczp
When I compile a Java project using IntelliJ IDEA, it gives me the following output (and error):

I'm quite confused confused by this! Below are my settings:

I changed my compiler to Eclipse and run my project. Afterwards changed back to Javac and problem solved. I don't know exact problem but it can help who is looking for solution.
我将编译器更改为 Eclipse 并运行我的项目。后来改回Javac，问题解决了。我不知道确切的问题，但它可以帮助正在寻找解决方案的人。

I solved this issue by increasing the default value(700) of Build process heap sizeon IntelliJ's compiler settings.
我通过在 IntelliJ 的编译器设置上增加Build 进程堆大小的默认值（700）来解决这个问题。

Changing the Language Level in the Project Settings (Ctrl + Alt + Shift + S) to Java 8 solved the problem for me
将项目设置中的语言级别（Ctrl + Alt + Shift + S）更改为 Java 8 为我解决了这个问题

- On Intellij IDEA Ctrl + Alt + Sto open settings.
- Build, Execution, Deployment-> Compiler-> Java Compiler
- choose your java version from Project bytecode version
- Uncheck Use compiler from module target JDK when possible
- click applyand ok.
- 在Intellij IDEA Ctrl + Alt + S上打开设置。
- 构建、执行、部署->编译器-> Java 编译器
- 从项目字节码版本中选择您的 Java版本
- 尽可能取消选中从模块目标 JDK 使用编译器
- 单击应用并确定。

You have to disabled the Javac Options: Use compiler from module target JDK when possible.
您必须禁用 Javac 选项：尽可能使用来自模块目标 JDK 的编译器。

In my case, using Java 11, I had:
就我而言，使用 Java 11，我有：
public List<String> foo() {
...
return response.readEntity(new GenericType<List<String>>() {});
and Intellij suggested I should use <>instead of GenericType<List<String>>, as such:
和 Intellij 建议我应该使用<>而不是GenericType<List<String>>，因此：
public List<String> foo() {
...
return response.readEntity(new GenericType<>() {});
I did that in four functions and the project stopped compiling with an internal compiler error, reverted and it compiled again. Looks like a bug with type inference.
我在四个函数中做到了这一点，项目停止编译并出现内部编译器错误，恢复并再次编译。看起来像类型推断的错误。

In my case it was because of lomboklibrary with intellij 2019.2 & java11.
就我而言，这是因为lombok带有 intellij 2019.2 和 java11的库。
According to this IDEA bugafter workaround idea works again:
根据此 IDEA 错误，解决方法的想法再次起作用：
Disable all building from intelliJ and dedicate the build to Maven.
Disable all building from intelliJ and dedicate the build to Maven.

For me the module's target bytecode version was set to 5. I changed it to 8 and the error is gone:
对我来说，模块的目标字节码版本设置为 5。我将其更改为 8，错误消失了：

In my case, it was response type in restTemplate:
就我而言，它是响应类型restTemplate：
ResponseEntity<Map<String, Integer>> response = restTemplate.exchange(
eurl,
HttpMethod.POST,
requestEntity,
new ParameterizedTypeReference<>() { <---- this causes error
}
);
Should be like this:
应该是这样的：
ParameterizedTypeReference<Map<String, Integer>> responseType = new ParameterizedTypeReference<>() {};
ResponseEntity<Map<String, Integer>> response = restTemplate.exchange(
url,
HttpMethod.POST,
requestEntity,
responseType
);
