maven編譯項目時出錯，提示信息如下：
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:testCompile (default-testCompile) on project springside-core: Compilation failure
[ERROR] No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?
[ERROR] -> [Help 1]

[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.

解決方案：
1，在eclipse的菜單中，進入 Window > Preferences > Java > Installed JREs ->Add ->Standard VM
jre home 選擇jdk安裝目錄，然后選中
2，右鍵項目build path
jdk是開發工具
jre是運行環境
編譯用的都是jdk的resources嘛，開發時不能只有運行庫，應該具備開發庫，就是這個意思。
另外***is not a servlet的錯
servlet和jsp的作用域加上就可以
