Error:java: Compilation failed: internal java compiler error

IntelliJ Idea编译报错：

 

Information:Using javac 1.7.0_79 to compile java sources
Information:java: javacTask: 源发行版 1.7 需要目标发行版 1.7
Information:java: Errors occurred while compiling module 'xxx'
Information:15/8/14 下午11:08 - Compilation completed with 1 error and 0 warnings in 1s 913ms
Error:java: Compilation failed: internal java compiler error

参考了附录中的文章，作如下修改（Idea版本14.1.4）：

 

File-->Other Settings-->Default Settings-->Compiler-->Java Compiler

在Per-module bytecode version下点击“+”，出现的Choose Module框中是空白，无法修改Target bytecode version.

选择项目，右击选择“Open Project Settings”-->Modules-->Language Level，改成6、7、Project Default都不起作用，折腾半天。

 

在Stackoverflow上偶然搜索到如下说明（http://stackoverflow.com/questions/12900373/idea-javac-source-release-1-7-requires-target-release-1-7）：

 

I've hit this after just minor upgrade from IntelliJ IDEA 14 to v14.1. For me changing an edit of top/parent pom helped and then clicked re-import Maven (if it is not automatic).

But it maybe just enough to Right Click on module(s)/aggregated/parent module and Maven -> Reimport.

选中项目，右击选择Maven-->Reimport, 再次编译，问题解决。

在idea中编译时发生如下的错误

Information:Using javac 1.7.0_75 to compile java sources Information:java: javacTask:源发行版1.6需要目标发行版1.6Information:java:Errors occurred while compiling module'kulong'Information:15/3/2613:22-Compilation completed with1 error and0 warnings in5s771msError:java:Compilation failed:internal java compiler error

解决办法

setting->Compiler->Java Compiler 设置相应Module的target byte code version的合适版本就行来。
