Question

在CAS@http://jasig.github.io/CAS/4.0.0/protocol/rest-protocol.html上按照说明启用REST API，在部署maven覆盖层时，我尝试发布到

我检查了@https://github.com/jasig/cas/blob/master/cas-server-integration-restlet/src/main/java/org/jasig/cas/integration/restlet/ticketresource.java代码，它看起来像

    /**
 * Log the form request.
 *
 * @param form the form
 */
private void logFormRequest(final Form form) {
    if (LOGGER.isDebugEnabled()) {
        final Set<String> pairs = new HashSet<String>();
        for (final String name : form.getNames()) {
            final StringBuilder builder = new StringBuilder();
            builder.append(name);
            builder.append(": ");
            if (!"password".equalsIgnoreCase(name)) {
                builder.append(form.getValues(name));
            } else {
                builder.append("*****");
            }
            pairs.add(builder.toString());
        }
        LOGGER.debug(StringUtils.join(pairs, ", "));
    }
}

有人有什么想法吗？谢了！

Maven引入了commons-lang-2.5.jar和commons-lang-2.1.jar。2.1不包括Restlet框架提供的方法签名。我删除了2.1版jar，冲突得到了解决。我正在使用的CAS 4.0的maven覆盖模板将其拉入。我确实告诉它自动解决依赖关系，所以最终是我的错。

如果你想知道我删除了：
