CentOS上的Apache Ant 1.8 [英] Apache Ant 1.8 on CentOS

问题描述

我试图让apache ant 1.8在CentOS下工作。首先，我有这个错误。

 错误：找不到或加载主类org.apache.tools.ant.launch.Launcher 
  

然后根据以下链接设置以下变量：

<一个href =https://stackoverflow.com/questions/4214979/ant-exception-in-thread-main-java-lang-noclassdeffounderror-org-apache-tools> Ant：线程主中的异常java.lang.NoClassDefFoundError：org / apache / tools / ant / launch / Launcher

不是CentOS，但是我确实验证了除JAVA_HOME之外的路径，所以我根据这个网站设置它：

https://serverfault.com/questions/50883/what-is-the-value-of-java-home-for-centos

现在我第一次遇到同样的错误。无论我使用哪种蚂蚁规则，我仍然收到相同的错误。

你可以在CentOS上克隆他，如果你想尝试：

解决方案

以下是在CentOS上安装ant 1.8所需的步骤：

1. 下载 http://archive.apache.org/dist/ant/binaries/apache-ant-1.8.4-bin.tar.gz


2. 将tarball复制到您的CentOS主文件夹（如果还没有）


3. tar xvzf apache-ant-1.8.4-bin.tar.gz


4. sudo mv apache-ant-1.8.4 / opt / ant


5. 设置ANT_HOME = / opt / ant


6. 添加' e xport ANT_HOME = / opt / ant '至 / etc / profile

要验证它是否有效，请运行：

  ant -version 
  

I am trying to get apache ant 1.8 to work under CentOS. First, I had this error.

Error: Could not find or load main class org.apache.tools.ant.launch.Launcher

Then I set the following variables according to this link:

Ant: Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/tools/ant/launch/Launcher

It's not CentOS, but I did verify the paths exist except JAVA_HOME, so I set it according to this site:

https://serverfault.com/questions/50883/what-is-the-value-of-java-home-for-centos

Now I am getting the same error I did the first time. It does not matter which ant rule I use, I still get the same error.

[bullshark]% export JAVA_HOME=/usr/lib/jvm/jre-1.7.0-openjdk.x86_64/
