Running...

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

And running...

mlittle-mbook1:bin mlittle$ export   JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home

I set java_home to: JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home

I have just noticed that Apache Ant is looking in the wrong path, with an additional ‘/'

And according to your email

“ Ant will try to use the file $JAVA_HOME/bin/java. If that doesn't exist, then > JAVA_HOME is not correct, it's that simple. If for example your java executable > is at /path/to/whatever/bin/java, then JAVA_HOME should be /path/to/whatever.”

or… $JAVA_HOME/bin/java

but the error message indicates that it is looking in the path..

$JAVA_HOME//bin/java

Notice the ‘//‘ instead of ‘/‘: how to correct this?

Or is there an ‘ant’ command, where I can force it to look in the correct path?

Thank you, you have resolved one issue for me, I understand that /java is an executable in the path $java_home/bin/java, not a folder As for $JAVA_HOME/bin/java -version, I got the following...

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

Now re-running ant to attempt to build the hybris instance...

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

As you can see, I am still having problems with 'ant' despite having what now appears the correct $java_home location.

== 初步调查

我在MacBook上的Java安装似乎有问题，因为这涉及到基于Java的电子商务平台[Difficulties with installation script for hybris 5.6.02]的安装和Apache Ant的使用

关于我的MacBook。。系统软件概述：

System Version: OS X 10.10.5 (14F27)
Kernel Version: Darwin 14.5.0
Boot Volume: Macintosh HD
Boot Mode: Normal
Computer Name: mlittle-mbook1
User Name: mlittle-mbook1 (mlittle)
Secure Virtual Memory: Enabled
Time since boot: 1 day5:34

=========

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

  3。然后我下载了JDK版本8、更新60，路径如下：

/Library/Java/Java？Java虚拟机

以前是

/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)

它仍然指示java版本“1.7.0_21”

所以我改名为/jdk1。7.0_21.jdk到/old-jdk1。7.0_21.jdk

4。我再次检查java的版本，然后得到…

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。这应该是适用于Hybris5的Java的正确版本。6.0.2[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

  试图把所有的。。并收到与JAVA_HOME相关的错误消息
 

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

   6。再次检查java路径…

mlittle-mbook1:platform mlittle$ which java /usr/bin/java

 

 7。我尝试更改Java_主路径，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

   8。再次选中“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_主页，重新运行Ant，但仍然收到一条错误消息

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_主页，重新运行Ant，但仍然收到错误消息

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

  <11>强壮。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java设置主变量：有什么建议吗

有 Java 编程相关的问题?
