我有一个奇怪的问题。我正在研究 Jenkins CasC 管道以在启动时自动填充作业。一切都很好，直到我开始添加参数。第一次从作业中运行添加的以下代码失败，然后当我随后重新运行时它起作用了。我发现的一个论坛指出，运行 Groovy 代码需要注册参数，这就是为什么从第二次构建开始就可以正常工作的原因。它还指出，通过 CasC 加载这个第一次错误不是问题。然而，通过 CasC 加载会产生以下错误。请注意，当从代码中保存并出现第一次错误时，确切的代码可以正常工作。
错误：

这是我的脚本：
pipeline {

parameters {
choice(name: 'app', choices: ['app1', 'app2'], description: 'Select the app.')
choice(name: 'app_year', choices: ['', '2023', '2022', '2021'], description: 'Select the app year.')
choice(name: 'deploy_env', choices: ['builds'], description: 'Default is builds.')
choice(name: 'feature', choices: ['', 'feat1', 'feat2', 'feat3'], description: 'Select the feature, leave blank for all.')
}
triggers {
cron('H/15 * * * *')
}
stages {
stage ('App Healthcheck') {
agent { label 'test-deploy01' }
options {
timeout(time: 3600, unit: 'SECONDS')
}
steps {
sh "cd /opt/tools/ansible/${app}/scripts/; \
PYTHONPATH=shared python app_service_check.py -y $app_year -e $deploy_env -p $feature"
}
}
}
}
我通过 GUI 粘贴了上面的内容。单击新建项目 --> 管道 --> 在页面上粘贴 groovy 脚本并保存。
第一次跑，报了上面的错误。然而，这确实在作业中注册了参数选项，现在我可以毫无问题地运行作业，并得到每个参数的提示，脚本也没有问题。
我需要通过 CasC 加载诸如此类的大量作业，但是由于上述错误，Jenkins 无法启动，因此我无法在 GUI 中重新运行该作业来解决此问题。
我该如何解决这个问题？
