Git SCM触发的管道的Jenkins BUILD_USER_ID缺少PropertyException

Question

我需要从 Jenkins 管道中获取BUILD_USER_ID，并使用本教程成功实现：这里

它在用户手动触发时工作，但在GitSCM触发时返回错误。

groovy.lang.MissingPropertyException:类：groovy.lang.Binding没有这样的属性：BUILD_USER_ID

请帮帮忙。

仅当生成具有UserIdCause时才设置BUILD_USER_ID：

https://github.com/jenkinsci/build-user-vars-plugin/blob/master/src/main/java/org/jenkinsci/plugins/builduser/BuildUser.java#L84-L88

UserIdCause userIdCause = (UserIdCause) build.getCause(UserIdCause.class);
        if(new UserIdCauseDeterminant().setJenkinsUserBuildVars(userIdCause, variables)) {
            return;
        }

https://github . com/Jenkins ci/build-user-vars-plugin/blob/master/src/main/Java/org/Jenkins ci/plugins/build user/var setter/impl/useridcausedeterminant . Java # L42

public boolean setJenkinsUserBuildVars(UserIdCause cause,
            Map<String, String> variables) {
        if(null != cause) {
            String username = cause.getUserName();
            UsernameUtils.setUsernameVars(username, variables);

            String userid = StringUtils.trimToEmpty(cause.getUserId());
            variables.put(BUILD_USER_ID, userid);

如果构建是由 SCMTrigger 触发的，您将没有BUILD_USER_ID，而是BUILD_USER：

https://github.com/jenkinsci/build-user-vars-plugin/blob/master/src/main/java/org/jenkinsci/plugins/builduser/BuildUser.java#L78

// set BUILD_USER_NAME to fixed value if the build was triggered by a change in the scm
        SCMTrigger.SCMTriggerCause scmTriggerCause = (SCMTrigger.SCMTriggerCause) build.getCause(SCMTrigger.SCMTriggerCause.class);
        if (new SCMTriggerCauseDeterminant().setJenkinsUserBuildVars(scmTriggerCause, variables)) {
            return;
        }

https://github.com/jenkinsci/build-user-vars-plugin/blob/master/src/main/java/org/jenkinsci/plugins/builduser/varsetter/impl/SCMTriggerCauseDeterminant.java#L15

public boolean setJenkinsUserBuildVars(SCMTriggerCause cause,
            Map<String, String> variables) {

        if (cause != null) {
            UsernameUtils.setUsernameVars("SCMTrigger", variables);

            return true;
        } else {
            return false;
        }
    }

https://github.com/jenkinsci/build-user-vars-plugin/blob/master/src/main/java/org/jenkinsci/plugins/builduser/utils/UsernameUtils.java#L28

public static void setUsernameVars(String username, Map<String, String> variables) {
        variables.put(BUILD_USER_VAR_NAME, username);
        variables.put(BUILD_USER_FIRST_NAME_VAR_NAME, getFirstName(username));
        variables.put(BUILD_USER_LAST_NAME_VAR_NAME, getLastName(username));
    }

为了克服这个问题，您可以在使用之前检查BUILD_USER_ID是否存在。
