java - CentOS 上的 Apache Ant 1.8

Question

我正在尝试让 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如下变量:

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

不是CentOS，但我确实验证了除JAVA_HOME之外的路径存在，所以我按照这个网站设置:

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

现在我遇到了与第一次相同的错误。无论我使用哪种 ant 规则，我仍然会遇到相同的错误。

[bullshark]% export JAVA_HOME=/usr/lib/jvm/jre-1.7.0-openjdk.x86_64/
[alpha:~]
[bullshark]% export ANT_HOME=/usr/share/ant/
[alpha:~]
[bullshark]% export PATH=$PATH:$ANT_HOME/bin
[alpha:~]
[bullshark]% cd JRobo 
[alpha:JRobo] on master
[bullshark]% ant clean-and-fat-jar 
Picked up _JAVA_OPTIONS: -Xmx64m

如果你想尝试，你可以在 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(如果它不在那里)
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
