一、
解決-Dmaven.multiModuleProjectDirectory system property is not set. Check $M2_HOME environment variable and mvn script match.
1.添加M2_HOME的環境變量
2.Preference->Java->Installed JREs->Edit 選擇一個jdk,
添加 -Dmaven.multiModuleProjectDirectory=$M2_HOME
-Dmaven.multiModuleProjectDirectory=$M2_HOME
二、ERROR: JAVA_HOME is set to an invalid directory
發現1:在JAVA_HOME的配置中多啦一個分號,
發現1:在JAVA_HOME中配置多啦\lib
三、No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?
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]
[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.
[ERROR] Re-run Maven using the -X switch to enable full debug logging.

解決方案:
- 下載java jdk,並安裝java jdk。下載地址:http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html
-
在eclipse的菜單中,進入 Window > Preferences > Java > Installed JREs > Execution Environments,選擇JavaSE-1.6, 在右側選擇jdk.
-
然後在maven菜單中使用 “update project ...”.
四、解決maven打包編譯出現File encoding has not been set問題
[WARNING] File encoding has not been set, using platform encoding GBK, i.e. build is platform dependent!
找了半天,原來只要在pom.xml文件中增加一個配置項即可
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
