与更新我的Mac最新的Java JDK困难 [英] Difficulties with updating my Mac to the latest Java JDK

问题描述

[二零一五年十月一十二日12:51]

  

运行...

 小mbook1：平台mlittle $蚂蚁清理所有
     错误：JAVA_HOME未正确定义。
       我们不能执行/Library/Java/JavaVirtualMachines/jdk1.7.0_21.jdk/Contents/Home//bin/java
 

  

和运行...

  mlittle-mbook1：斌mlittle $出口JAVA_HOME = /图书馆/的Java / JavaVirtualMachines / jdk1.8.0_60.jdk /内容/首页
 

  

我JAVA_HOME设置为：
  JAVA_HOME = /图书馆/的Java / JavaVirtualMachines / jdk1.8.0_60.jdk /内容/首页

  
  

我刚才注意到，Apache Ant是找错了路，一个额外的/

  
  

和根据您的电子邮件

  
  

蚂蚁会尝试使用文件$ JAVA_HOME /斌/ java的。如果不存在，那么> JAVA_HOME是不正确的，就这么简单。例如，如果您的Java可执行文件>的是/路径/到/不管/斌/ java中，那么JAVA_HOME应该是/路径/到/不管。

  
  

或...
      $ JAVA_HOME /斌/ java的

  
  

但错误信息表明它正在寻找路径。

  $ JAVA_HOME //斌/ java的
 

  

注意'//'，而不是'/'？如何纠正这种

  
  

还是有一位蚁族命令，在那里我可以强制它在正确的路径看？

感谢你，你已经解决了一个问题对我来说，我的理解是/是java路径$ JAVA_HOME可执行/斌/ java的，而不是一个文件夹
  至于$ JAVA_HOME /斌/ Java的版本，
  我得到了以下...

  mlittle-mbook1：〜mlittle $的/ usr / libexec中/ JAVA_HOME -v
JAVA_HOME：选项需要一个参数 -  v
/Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home
mlittle-mbook1：〜mlittle $哪个Java
在/ usr /斌/ java的
 

  

现在重新运行蚂蚁试图建立采用hybris实例...

  mlittle-mbook1：〜mlittle $ CD 00hybris /的hybris /斌/平台
mlittle-mbook1：平台mlittle $ PWD
/用户/ mlittle / 00hybris /的hybris /斌/平台

mlittle-mbook1：平台mlittle $蚂蚁清理所有
错误：JAVA_HOME未正确定义。
我们不能执行/Library/Java/JavaVirtualMachines/jdk1.7.0_21.jdk/Contents/Home//bin/java
 

  

正如你所看到的，我仍然有蚁族问题，尽管有现在看来正确的$ JAVA_HOME位置。

3。然后我下载的JDK版本8，更新60，因此在路径：

/库/的Java / Java的？JavaVirtualMachines

previously它有..

  

/jdk1.7.0_21.jdk

现在它

  

/jdk1.7.0_21.jdk结果
  /jdk1.8.0_60.jdk

这是混乱的，我期待它会取代/jdk1.7.0_21.jdk
 与/jdk1.8.0_60.jdk

4。我检查了Java ..版本

  mlittle-mbook1：〜mlittle $ Java的版本
Java版本1.7.0_21
mlittle-mbook1：〜mlittle $ Java的版本
Java版本1.7.0_21
的Java（TM）SE运行时环境（建立1.7.0_21-B12）

mlittle-mbook1：平台mlittle $蚂蚁清理所有
错误：JAVA_HOME未正确定义。
  我们不能执行/Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home/bin/bin/java
 

11。再次检查的Java

  mlittle-mbook1：平台mlittle $哪个Java
在/ usr /斌/ java的
 

我很困惑，明明我没有我的Java设为首页变量设置正确：有什么建议？

解决方案

看起来这应该是正确的：

 出口JAVA_HOME = /图书馆/的Java / JavaVirtualMachines / jdk1.8.0_60.jdk /内容/首页
 

Ant将尝试使用文件 $ JAVA_HOME /斌/ java的。如果不存在，那么 JAVA_HOME 是不正确的，就这么简单。
例如，如果你的的Java 可执行程序位于 /路径/到/不管/斌/ java的，那么 JAVA_HOME 应 /路径/到/不管。

[2015-10-12 12:51]

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?

=================

[2015-10-12: 1204]

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.

== INITIAL INVESTIGATION

I seem to have a problem with my Java installation on my MacBook, as this relates to the installation of a java based eCommerce platform [ Difficulties with installation script for hybris 5.6.02 ] and the use of Apache Ant...

1. Regarding my MacBook.. System Software Overview:

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. Checked which java…

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


2. Recheck which 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. I then downloaded the JDK version 8, update 60, and so in the path:

/Library/Java/Java?JavaVirtualMachines

Previously it had..

/jdk1.7.0_21.jdk

Now It has

/jdk1.7.0_21.jdk
/jdk1.8.0_60.jdk

This is confusing, I was expecting that it would replace /jdk1.7.0_21.jdk with /jdk1.8.0_60.jdk

4. I check the version of java..

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)

It was still indicating java version "1.7.0_21"???

And so I renamed /jdk1.7.0_21.jdk to /old-jdk1.7.0_21.jdk

4. I again check the version of java, and then I got…

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. Which should be the correct version of Java for Hybris5.6.0.2 [this the java based eCommerce platform that I am trying to install] by setting the ANT environment variables, and commence the build process [ant clean all]… but…

mlittle-mbook1:platform mlittle$ . ./setantenv.sh


 Tried to ant clean all.. and got an error message relating to JAVA_HOME



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. Again checked the java path…

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





7. I tried to change the Java_home path and then re-run 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. Again checked "which 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.I tried to change the Java_home, reran Ant, but still got an error message..

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.I tried to change the Java_home, reran Ant, but still got an error message..

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. Again checked which java

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

I am confused, clearly I do not have my java set home variables set up properly: any suggestions?

解决方案

Looks like this should be the correct one:

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home

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.
