由于路径重复导致无法正确读取到Jar

解决办法：修改源码重新编译Dolphinscheduler3.2.1，替换dolphinscheduler-task-api-3.2.1.jar

package org.apache.dolphinscheduler.plugin.task.api.shell

//BaseLinuxShellInterceptorBuilder类的 

private String shellBody() {
        if (CollectionUtils.isEmpty(scripts)) {
            return StringUtils.EMPTY;
        }
        String scriptBody = scripts
                .stream()
                .collect(Collectors.joining(System.lineSeparator()));
        //新增去除重复路径
        if(scriptBody.contains(".jar")){
            log.info("确保去除重复路径");
            scriptBody = scriptBody.replace(shellDirectory+"//","/");
        }
        scriptBody = scriptBody.replaceAll("\\r\\n", System.lineSeparator());
        return ParameterUtils.convertParameterPlaceholders(scriptBody, propertyMap);
    }

替换重启就正常了
