No compiler is provided in this environment. Perhaps you are running on a JRE rather than a jdk?

关于maven项目中出现：No compiler is provided in this environment. Perhaps you are running on a JRE rather than a jdk?

在eclipse中依次选择window->preferences->java->installed jres，图中箭头所指的location一定要是jdk路径而不是jre路径。我原来就是jre路径，才导致项目在install时报错，改成jdk路径就正确了。
