CentOS上的Apache Ant 1.8

Question

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

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

然后我根据这个链接设置以下变量：

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

这不是CentOS，但我确实验证了除JAVA_HOME之外的路径，所以我根据这个网站设置了它：

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

现在我遇到了第一次犯的错误。我使用哪个蚂蚁规则并不重要，我仍然会得到同样的错误。

[bullshark]% export JAVA_HOME=/usr/lib/jvm/jre-1.7.0-openjdk.x86_64/
[alpha:~]
[bullshark]% export ANT_HOME=/usr/share/ant/

[bullshark]% export PATH=$PATH:$ANT_HOME/bin

如果您想尝试，可以在CentOS上克隆他：

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（如果它还没有）
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. 将“export ANT_HOME=/opt/ant”添加到/etc/profile

要验证它是否有效，请运行：

ant -version
