3.轻量级检查的名词解释
英文描述
If selected, try to obtain the Pipeline script contents directly from the SCM without performing a full checkout. The advantage of this mode is its efficiency; however, you will not get any changelogs or polling based on the SCM. (If you use checkout scm during the build, this will populate the changelog and initialize polling.) Also build parameters will not be substituted into SCM configuration in this mode. Only selected SCM plugins support this mode.
中文描述
如果选中，请尝试直接从SCM获取管道脚本内容，而不执行完全签出。这种模式的优点是效率高；但是，您不会得到任何基于SCM的变更日志或轮询。（如果在构建期间使用checkout scm，这将填充变更日志并初始化轮询。）在这种模式下，构建参数也不会被替换到SCM配置中。只有选定的SCM插件支持此模式。
