如何使用Maven在Mac OS X 10.7.4 64位上构建32位

Question

I have just got a Mac BookPro with os OS X Lion which has maven pre installed with the version

#mvn --version
Apache Maven 3.0.3 (r1075438; 2011-02-28 19:31:09+0200)
Maven home: /usr/share/maven
Java version: 1.6.0_31, vendor: Apple Inc.
Java home: /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
Default locale: tr_TR, platform encoding: MacTurkish
OS name: "mac os x", version: "10.7.4", arch: "x86_64", family: "mac"

When I run a

mvn clean install

maven is somehow failing compiling. One of the fail reason is : java.lang can not found.

When I check java settings I saw that there is both 64 and 32 bit java versions. thanks.

In the Java properties :

There are two Java instances

Java SE Apple Inc. 64 Bits 1.6.0_31-b04-415

Java SE Apple Inc. 64 Bits 1.6.0_31-b04-415

Answer 1

First try to write HelloWord.java and compile it using command line javac HelloWord.java .

If it works move towards maven. Check environment variable JAVA_HOME that is used by maven to find java. I believe it points to "wrong" java version. Fix this and try again. I hope this will work.
