Failed to run CloneWorks from other directory after change INSTALL_DIR

[Xiaoven]

The path of CloneWorks on my computer is /home/USER_NAME/opt/CloneWorks.

OS: Ubuntu 18.04

With the default config where INSTALL_DIR=., the example test works ok.

Problematic config

Then I set INSTALL_DIR=/home/USER_NAME/opt/CloneWorks, and add export PATH="/home/USER_NAME/opt/CloneWorks/cwbuild:$PATH" to ~/.zshrc.

Failure

I tried cwbuild -i sources -f sources/files -b sources/blocks -l java -g function -c type3line > cwbuild.log in another directory, but I got the following errors (Exception: Broken pipe and Exception: Stream closed ):

CloneWorks Version 1.0

Additional Info for debug

I log INSTALL_DIR and LIBS in cwbuild.

With the default setting, their values are:

INSTALL_DIR is  .
LIBS is  ./bin/:./libs/commons-lang3-3.4/commons-lang3-3.4.jar:./libs/commons-exec-1.3/commons-exec-1.3.jar:./libs/commons-cli-1.3.1/commons-cli-1.3.1.jar:./libs/commons-io-2.4/commons-io-2.4.jar
"./cfprocessors/txl_normalization" "r" "." "java" "function" extract

After modification, they are:

INSTALL_DIR is  /home/USER_NAME/opt/CloneWorks
LIBS is  /home/USER_NAME/opt/CloneWorks/bin/:/home/USER_NAME/opt/CloneWorks/libs/commons-lang3-3.4/commons-lang3-3.4.jar:/home/USER_NAME/opt/CloneWorks/libs/commons-exec-1.3/commons-exec-1.3.jar:/home/USER_NAME/opt/CloneWorks/libs/commons-cli-1.3.1/commons-cli-1.3.1.jar:/home/USER_NAME/opt/CloneWorks/libs/commons-io-2.4/commons-io-2.4.jar
