我在Ubuntu 16.04上运行Jenkins 2.140服务器，以及使用Ansible 2.6.2的Ansible AWX 1.0.7.2服务器。
我正在Jenkins中创建一个作业，它在我的Ansible AWX服务器上运行一个模板。我还有其他几个Jenkins作业，它们运行的模板都可以工作，所以我知道我为此使用的一般配置是可以的
然而，当我使用使用JobDSL的种子作业创建Jenkins作业时，该作业在Ansible AWX步骤失败，输出为：
11:50:42 [EnvInject] - Loading node environment variables.

这个输出实际上并没有给我任何可以使用的东西，尤其是因为我不是Java专家。
我手动配置Jenkins作业，一切都很好。这是工作作业的config.xml(仅AWX部分(。请注意，所有这些额外的变量都是在作业的早期作为参数传入的：
<builders>
<org.jenkinsci.plugins.ansible__tower.AnsibleTower plugin="ansible-tower@0.9.0">
<towerServer>AWX Server</towerServer>
<jobTemplate>create-ec2-instance</jobTemplate>

</extraVars>
<jobTags/>

<removeColor>false</removeColor>
<templateType>job</templateType>
<importWorkflowChildLogs>false</importWorkflowChildLogs>
</org.jenkinsci.plugins.ansible__tower.AnsibleTower>
</builders>
来自失败的JobDSL生成的作业的config.xml，在我看来是一样的：
<builders>
<org.jenkinsci.plugins.ansible__tower.AnsibleTower>
<towerServer>AWX Server</towerServer>
<jobTemplate>create-ec2-instance</jobTemplate>
<jobType>run</jobType>
<templateType>job</templateType>
<extraVars>
key_name: ${key_name} ec2_termination_protection: ${ec2_termination_protection} vpc_subnet_id: ${vpc_subnet_id} security_groups: ${security_groups} instance_type: ${instance_type} instance_profile_name: ${instance_profile_name} assign_public_ip: ${assign_public_ip} region: ${region} image: ${image} instance_tags: ${instance_tags} ec2_wait_for_create: ${ec2_wait_for_create} ec2_wait_for_create_timeout: ${ec2_wait_for_create_timeout} exact_count: ${exact_count} delete_volume_on_termination: ${delete_volume_on_termination} data_disk_size: ${data_disk_size} private_domain: ${private_domain} route53_private_record_ttl: ${route53_private_record_ttl} dns_record: ${dns_record} elastic_ip: ${elastic_ip}
</extraVars>
<verbose>true</verbose>
<importTowerLogs>true</importTowerLogs>
</org.jenkinsci.plugins.ansible__tower.AnsibleTower>
</builders>
因此，JobDSL生成的作业总是会有一些预期的差异，比如缺少空字段，但我们所有(成功的(其他作业都遵循这个过程。
JobDSL脚本在这里：
configure { project ->
project / 'builders ' << 'org.jenkinsci.plugins.ansible__tower.AnsibleTower' {
towerServer 'AWX Server'
jobTemplate ('create-ec2-instance')
templateType 'job'
jobType 'run'
extraVars('''key_name: ${key_name}
ec2_termination_protection: ${ec2_termination_protection}
vpc_subnet_id: ${vpc_subnet_id}
security_groups: ${security_groups}
instance_type: ${instance_type}
instance_profile_name: ${instance_profile_name}
assign_public_ip: ${assign_public_ip}
region: ${region} image: ${image}
instance_tags: ${instance_tags}
ec2_wait_for_create: ${ec2_wait_for_create}
ec2_wait_for_create_timeout: ${ec2_wait_for_create_timeout}
exact_count: ${exact_count}
delete_volume_on_termination: ${delete_volume_on_termination}
data_disk_size: ${data_disk_size}
private_domain: ${private_domain}
route53_private_record_ttl: ${route53_private_record_ttl}
dns_record: ${dns_record}
elastic_ip: ${elastic_ip}''')
verbose 'true'
importTowerLogs 'true'
}
}
在我看来，这生成的作业在UI(以及XML(中看起来是相同的，但当我运行它时，我总是失败。很明显，我错过了一些东西，但如果我看到了什么，我一辈子都做不到。
尽管其他AWX作业都是在没有此功能的情况下构建的，但我添加了缺失的(空(字段，作业开始成功。
因此，将我的JobDSL脚本更改为：
configure { project ->
project / 'builders ' << 'org.jenkinsci.plugins.ansible__tower.AnsibleTower' {
towerServer 'AWX Server'
jobTemplate ('create-ec2-instance')
extraVars('''key_name: ${key_name}
ec2_termination_protection: ${ec2_termination_protection}
vpc_subnet_id: ${vpc_subnet_id}
security_groups: ${security_groups}
instance_type: ${instance_type}
instance_profile_name: ${instance_profile_name}
assign_public_ip: ${assign_public_ip}
region: ${region}
image: ${image}
instance_tags: ${instance_tags}
ec2_wait_for_create: ${ec2_wait_for_create}
ec2_wait_for_create_timeout: ${ec2_wait_for_create_timeout}
exact_count: ${exact_count}
delete_volume_on_termination: ${delete_volume_on_termination}
data_disk_size: ${data_disk_size}
private_domain: ${private_domain}
route53_private_record_ttl: ${route53_private_record_ttl}
dns_record: ${dns_record}
elastic_ip: ${elastic_ip}''')
jobTags ''
skipJobTags ''
jobType 'run'
limit ''
inventory ''
credential ''
verbose 'true'
importTowerLogs 'true'
removeColor ''
templateType 'job'
importWorkflowChildLogs ''
现在正在按预期工作。
