Eclipse中用Maven編譯報錯的解決方法
環境】
eclipse-jee-juno-SR2-win32-x86_64
apache-maven-3.0.4
【Eclipse報錯】
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile (default-compile) on project sxf_transaction: Compilation failure [ERROR] Unable to locate the Javac Compiler in: [ERROR] C:\Program Files\Java\jre6\..\lib\tools.jar [ERROR] Please ensure you are using JDK 1.4 or above and [ERROR] not a JRE (the com.sun.tools.javac.Main class is required). [ERROR] In most cases you can change the location of your Java [ERROR] installation by setting the JAVA_HOME environment variable. [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.

【原因】
根據錯誤提示，需要JDK而不是JRE，並且需1.4以上版本。Eclipse的默認運行環境是JRE，而Maven編譯需要JDK。
【排錯】
1. 在cmd中用命令echo %JAVA_HOME%查看環境變量，指向正確。
2. 修改eclipse.ini文件，加入下面2句，依然不起作用。
-vm
C:\Program Files\Java\jdk1.7.0_02\bin\javaw.exe
-startup plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar --launcher.library plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.200.v20120522-1813 -showsplash org.eclipse.platform --launcher.XXMaxPermSize 256m -vm C:\Program Files\Java\jdk1.7.0_02\bin\javaw.exe --launcher.defaultAction openFile -vmargs -Xms40m -Xmx512m
3. 在Eclipse->Window->Preferences->Java->Installed JREs->Add...->Standard VM里，JRE home選擇
JDK的目錄。再勾選，如下圖，問題解決。

成功的話是這個樣子的，今天遇到這個問題，害我郁悶+糾結了好久。謝謝原作者啦。
