我正在尝试在詹金斯内部运行此命令。
sh 'docker run --name container_name -p 3306:3306 -e MYSQL_ROOT_PASSWORD=root -d mysql:8.0 --character-set-server=utf8mb4 --collation-server=utf8mb4_0900_ai_ci --sql-mode='''
但是
--sql-mode='''--sql-mode='--sql-mode='''这是完整的错误：

docker 容器似乎是从 jenkins 日志创建的，但不知道问题是什么
我猜你在单引号内。考虑阅读 https://groovy-lang.org/syntax.html#all-strings 和 https://www.gnu.org/software/bash/manual/html_node/Quoting.html .
我猜这个错误是由于 groovy 中奇怪的语法错误字符串构造造成的。
def example = '.....stuff.... ' ''
# two strings side by side - what to do with them in groovy?
def valid = 'stuff' + ''
# you could add two strings, but side by side is invalid.
只需删除引号即可，空引号在 shell 中无论如何都是空的。
sh 'docker run --name container_name -p 3306:3306 -e MYSQL_ROOT_PASSWORD=root -d mysql:8.0 --character-set-server=utf8mb4 --collation-server=utf8mb4_0900_ai_ci --sql-mode='
您可以使用双引号或使用 groovy 中的三引号字符串。
sh 'docker run --name container_name -p 3306:3306 -e MYSQL_ROOT_PASSWORD=root -d mysql:8.0 --character-set-server=utf8mb4 --collation-server=utf8mb4_0900_ai_ci --sql-mode=""'
注意，首先是 Jenkins 进行变量扩展，然后是 shell 进行变量扩展，它们是完全独立的扩展，具有不同的规则。
