Liquibase 4.20 不支持 sql 文件上的 pt-osc，正如预期的那样

Question

我遵循了以下设置步骤，但 alter 没有按预期使用 pt-osc

设置：

mkdir -p /liquibase/lib && export PATH=“/liquibase/lib:${PATH}”

curl -o /liquibase/lib/liquibase-percona.jar ``https://xyz/liquibase-percona-4.20.0.jar

curl -o /liquibase/lib/mysql-connector-java-5.1.48.jar ``https://xyz/mysql-connector-java-5.1.48.jar

curl ``https://xyz/liquibase-4.20.0.tar.gz`` | tar -xzv -C /liquibase/lib

yum install -y -q -e 1 libxslt

&& rpm -i ``https://xyz/jre-8u241-linux-x64.rpm

curl -o /liquibase/percona-toolkit ``https://axyz/percona-toolkit-3.5.1-2.el7.x86_64.rpm

ln -s /liquibase/percona-toolkit/bin/pt-online-schema-change /usr/local/bin/pt-online-schema-change

validation:

liquibase]# ls -lah

drwx------. 3 root root 17 Apr 10 19:33 percona-toolkit

pt-osc bin 按预期工作：

/liquibase/percona-toolkit/bin/pt-online-schema-change

Usage: pt-online-schema-change [OPTIONS] DSN

Errors in command-line arguments:
