如何修复 java lang.ClassNotFoundException：org.apache.tools.ant.taskdefs.Execute

Question

我目前正在使用 Quick Books Online SDK，他们的一些代码抛出 class 未找到错误。有没有人运行遇到过这个问题或类似的问题？

我查看了他们的 HelloWorld 应用程序示例，没有发现与我当前的实现有任何不同。而且，我真的只需要他们的默认配置。

导致错误的方法=>>

/**
 * Extracts environment properties on a JRE &lt; 1.5. This implementation
 * uses ant for this purpose.
 */
void extractProperties14()
{
    extractPropertiesFromCollection(Execute.getProcEnvironment());
}

Answer 1

您可能遇到与应用程序缺少库相关的问题 classpath

所以基本上你可以尝试两种选择：

找到兼容版本并在您的class路径

Apache Ant Core

尝试将您的 apache-commons-configuration 1.6 升级到 apache-commons-configuration 1.10，这不需要 Execute class。

这里是EnvironmentConfiguration目前1.10版本的源代码：

/**
 * Create a Configuration based on the environment variables.
 *
 * @see System#getenv()
 */
public EnvironmentConfiguration()
{
    super(new HashMap<String, Object>(System.getenv()));
}

当然你要测试和验证升级版本是否会导致运行时不兼容。
