本文介绍了解决Jenkins部署WAR包时遇到的编译错误问题。错误原因是代码中返回类型不匹配，通过显式类型转换解决了问题并成功构建。

处理jenkins部署war的时候出现如下错误：

[INFO] -------------------------------------------------------------
[ERROR] COMPILATION ERROR :

判断是不是代码中类型问题，开发业务的人说自己maven正常，还是让开发人员尝试修改代码，查看代码：

        public Long incr(final String key) {
                return 10000L;

              return strRedisTemplate.execute(new RedisCallback() {
                      @Override
                      public Long doInRedis(RedisConnection connection) throws DataAccessException {
                              connection.setNX(key.getBytes(), "100000".getBytes());
                              Long rs = connection.incr(key.getBytes());
                              return rs;
                      }
              });
        }

修改为：
        public Long incr(final String key) {
                return 10000L;

              return (Long)strRedisTemplate.execute(new RedisCallback() {
                      @Override
                      public Long doInRedis(RedisConnection connection) throws DataAccessException {
                              connection.setNX(key.getBytes(), "100000".getBytes());
                              Long rs = (Long)connection.incr(key.getBytes());
                              return rs;
                      }
              });
        }

修改后重启构建，果然成功了。

BUILD SUCCEED
