Hi,
In start-client.sh, I only define IOTDB_HOME. Also users do not need to read source code in client.sh, I think start-client.sh is ok. if [ -z "${IOTDB_HOME}" ]; then export IOTDB_HOME="$(cd "`dirname "$0"`"/..; pwd)" fi MAIN_CLASS=org.apache.iotdb.cli.client.Client CLASSPATH="" for f in ${IOTDB_HOME}/lib/*.jar; do CLASSPATH=${CLASSPATH}":"$f done And Jack Tsai, can you add following statements to your start-client.bat? It is very strange that i never define IOTDB_CLI_HOME, how can start-client.bat use this variable? Did you define this variable by youself? echo %IOTDB_HOME% echo %IOTDB_CLI_HOME% REM For each jar in the IOTDB_HOME lib directory call append to build the CLASSPATH variable. for %%i in ("%IOTDB_HOME%\lib\*.jar") do call :append "%%i" On 5/25/2019 12:49,Xiangdong Huang<saint...@gmail.com> wrote: Hi XuYi, At least I think there is something wrong in the start-cli.sh, please read the following code snippet in start-cli.sh: ``` CLASSPATH="" for f in ${IOTDB_HOME}/lib/*.jar; do CLASSPATH=${CLASSPATH}":"$f done ``` If I am a user and I just run the cli on my laptop to connect an IoTDB Server, I think I do not need to install IoTDB module, so there is no jars in `${IOTDB_HOME}/lib`.

It just help users to find which directory to run command like ' .\bin\start-client.bat'. I never defined 'IOTDB_CLI_HOME' variable neither in start-client.sh nor start-client.bat. I tried on My PC, it starts normally. Can you provide some snapshots to indicate how you package iotdb-cli and how to run start-client.bat? You can upload these picture to jira issue. ------------------------------------------------------------------------ In My environment, IOTDB_CLI_HOME is D:\workspace\java\incubator-iotdb\iotdb-cli\cli My output is : PS D:\workspace\java\incubator-iotdb\iotdb-cli\cli> .\bin\start-client.bat ```````````````````````` Starting IoTDB Client ```````````````````````` Require more params input, eg. ./start-client.sh(start-client.bat if Windows) -h xxx.xxx.xxx.xxx -p xxxx -u xxx.

I can not reproduce your issue on my MacOS.. The similar report on [1] may be caused if your maven building process is interrupted. But after reading the source code of `start-client.sh`, I think your solution 2 is needed: Now, `start-client.sh` requires copying jars from the `iotdb` module rather than just from the `iotdb-cli` module. That does not make sense. We are very glad to see the coming PR from you.

I found a problem when I start the IoTDB's client, and I think my problem is the same as the user in this mail: https://www.mail-archive.com/dev@iotdb.apache.org/msg00913.html Even if you have make some changes to the documentation on the website, it would still make users confused. When I follow the instruction on the website, it said that: # Windows $IOTDB_CLI_HOME\bin\start-client.bat -h <IP> -p <PORT> -u <USER_NAME> However, this would result in "Cannot find the main class 'org.apache.iotdb.cli.client.Client' error". After I look into the code of start-client batch file and script, I found the same problem as the user in the email above: https://gist.github.com/jack870131/eb778d0c5fadc8412e7d842abfb5de6d The reason is that the required jars to start IoTDB client are not in the correct lib directory. These are some solutions I found: 1. Copy all the jars in "/xxx/incubator-iotdb/iotdb-cli/cli/lib" to "/xxx/incubator-iotdb/iotdb/iotdb/lib". 2. Change the part of the code "for %%i in ("%IOTDB_HOME%\lib\*.jar")" into "for %%i in ("%IOTDB_CLI_HOME%\lib\*.jar")" 3. Do some changes to the documentation I think this error is because the way of starting the IoTDB version in Apache-incubator is different from the version in THU Lab. To start the old version, the batch file and script can go without error. However, the directory config has been changed in the Apache version, which I think you should make the documentation clearer or do some changes in the batch file and script. If you think this would count as an issue, I would like to join and contribute for it. Best regards, Tsung-Han Tsai
