...运行
little-mbook1:platform mlittle$ ant clean all
Error: JAVA_HOME is not defined correctly.
We cannot execute /Library/Java/JavaVirtualMachines/jdk1.7.0_21.jdk/Contents/Home//bin/java
跑步......
mlittle-mbook1:bin mlittle$ export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home
我将java_home设置为: JAVA_HOME = /库/爪哇/ JavaVirtualMachines / jdk1.8.0_60.jdk /内容/首页
我刚刚注意到Apache Ant正在寻找错误的路径,还有一个额外的'/'
根据您的电子邮件
“Ant将尝试使用$ JAVA_HOME / bin / java文件。如果不存在,那么> JAVA_HOME不正确,就这么简单。例如,如果你的java可执行文件>在/ path / to / whatever / bin / java,然后JAVA_HOME应该是/ path / to / whatever。“
...或 $ JAVA_HOME / bin中/ JAVA
但是错误消息表明它正在寻找路径..
$JAVA_HOME//bin/java
注意'//'而不是'/':如何纠正?
或者是否有'ant'命令,我可以强制它查看正确的路径?

谢谢,你已经为我解决了一个问题,我明白/ java是$ java_home / bin / java路径中的可执行文件,而不是文件夹 至于$ JAVA_HOME / bin / java -version, 我得到了以下内容......
mlittle-mbook1:~ mlittle$ /usr/libexec/java_home -v
java_home: option requires an argument -- v
/Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home
mlittle-mbook1:~ mlittle$ which java
/usr/bin/java
现在重新运行ant以尝试构建hybris实例......
mlittle-mbook1:~ mlittle$ cd 00hybris/hybris/bin/platform
mlittle-mbook1:platform mlittle$ pwd
/Users/mlittle/00hybris/hybris/bin/platform
mlittle-mbook1:platform mlittle$ . ./setantenv.sh
mlittle-mbook1:platform mlittle$ ant clean all
Error: JAVA_HOME is not defined correctly.
We cannot execute /Library/Java/JavaVirtualMachines/jdk1.7.0_21.jdk/Contents/Home//bin/java
正如您所看到的,我仍然遇到过“蚂蚁”问题。尽管现在看起来正确的$ java_home位置。

== 初步调查
我的MacBook上的Java安装似乎有问题,因为这与基于java的电子商务平台[Difficulties with installation script for hybris 5.6.02]的安装以及Apache Ant的使用有关......
系统版本:OS X 10.10.5(14F27)
内核版本:达尔文14.5.0
启动音量:Macintosh HD
启动模式:正常
计算机名称:mlittle-mbook1
用户名:mlittle-mbook1(mlittle)
安全虚拟内存:已启用
启动时间:1天5:34
======
1。检查了哪个java ...
mlittle-mbook1:~ mlittle$ which java
/usr/bin/java
2。重新检查哪个Java ..
mlittle-mbook1:~ mlittle$ ls -l `which java`
lrwxr-xr-x 1 root wheel 74 5 Nov 2014 /usr/bin/java -> /System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java
第3。然后我在路径中下载了JDK版本8,更新60,等等:
/库/爪哇/爪哇?JavaVirtualMachines
以前它有.. ..
/jdk1.7.0_21.jdk
现在有了
/jdk1.7.0_21.jdk
/jdk1.8.0_60.jdk
这令人困惑,我原以为它会取代/jdk1.7.0_21.jdk 使用/jdk1.8.0_60.jdk
4。我检查了java的版本..
mlittle-mbook1:~ mlittle$ java -version
java version "1.7.0_21"
mlittle-mbook1:~ mlittle$ java -version
java version "1.7.0_21"
Java(TM) SE Runtime Environment (build 1.7.0_21-b12)
Java HotSpot(TM) 64-Bit Server VM (build 23.21-b01, mixed mode)
它仍然表示java版本“1.7.0_21" ???
所以我将/jdk1.7.0_21.jdk重命名为/old-jdk1.7.0_21.jdk
4。我再次检查java的版本,然后我得到了......
mlittle-mbook1:~ mlittle$ java -version
java version "1.8.0_60"
Java(TM) SE Runtime Environment (build 1.8.0_60-b27)
Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode)
5。哪个应该是Hybris5.6.0.2的Java的正确版本[这是我试图安装的基于java的电子商务平台]通过设置ANT环境变量,并开始构建过程[ant clean all] ...但是...
mlittle-mbook1:platform mlittle$ . ./setantenv.sh
试图蚂蚁清理所有..并得到一个与JAVA_HOME有关的错误信息
mlittle-mbook1:platform mlittle$ ant clean all
Error: JAVA_HOME is not defined correctly.
We cannot execute /Library/Java/JavaVirtualMachines/jdk1.7.0_21.jdk/Contents/Home//bin/java
的 6。再次检查java路径......
mlittle-mbook1:platform mlittle$ which java
/usr/bin/java
7。我尝试更改Java_home路径,然后重新运行ANT。。
mlittle-mbook1:platform mlittle$ export JAVA_HOME=/Library/Java/Home
mlittle-mbook1:platform mlittle$ ant clean all
Error: JAVA_HOME is not defined correctly.
We cannot execute /Library/Java/Home/bin/java
的 8。再次检查“哪个Java”
mlittle-mbook1:platform mlittle$ which java
/usr/bin/java
mlittle-mbook1:platform mlittle$ $JAVA_HOME/bin/java -version
-bash: /Library/Java/Home/bin/java: No such file or directory
9.我试图更改Java_home,重新启用Ant,但仍然收到错误消息..
mlittle-mbook1:platform mlittle$ export JAVA_HOME=/Library/Java/JavaVirtualMachines/
mlittle-mbook1:platform mlittle$ ant clean all
Error: JAVA_HOME is not defined correctly.
We cannot execute /Library/Java/JavaVirtualMachines//bin/java
10。 9.我试图更改Java_home,重命令Ant,但仍然收到错误信息..
mlittle-mbook1:platform mlittle$ export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home/bin
mlittle-mbook1:platform mlittle$ ant clean all
Error: JAVA_HOME is not defined correctly.
We cannot execute /Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home/bin/bin/java
的 11。再次检查哪个java
mlittle-mbook1:platform mlittle$ which java
/usr/bin/java
我很困惑,显然我没有正确设置我的java设置主变量:有什么建议吗?
答案 0 :(得分:3)
看起来这应该是正确的:
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home
Ant将尝试使用文件$JAVA_HOME/bin/java
。如果这不存在,则JAVA_HOME
不正确,就这么简单。
例如,如果您的java
可执行文件位于/path/to/whatever/bin/java
,则JAVA_HOME
应为/path/to/whatever
。
