我正在尝试使用cobertura插件生成代码覆盖率报告.
我在pom.xml中有这种依赖
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>cobertura-maven-plugin</artifactId>
<version>2.6</version>
<executions>
<execution>
<phase>test</phase>
<goals>
<goal>cobertura</goal>
</goals>
<configuration>

</formats>
</configuration>
</execution>
</executions>
<configuration>
<formats>
<format>html</format>
<format>xml</format>
</formats>
</configuration>
当我使用这个目标构建我的项目-U -B清理安装cobertura：cobertura时,我在我的jenkins CI上得到以下错误
16:37:31 [ERROR] Failed to execute goal org.codehaus.mojo:cobertura-maven-plugin:2.6:instrument (default-cli) on project TestModule: Unable to execute Cobertura. Error while executing process.

在我的Windows机器上构建成功但在jenkins上失败了.当我将cobertura版本降级到2.5.1时,这个错误消失了,但我得到了一些解析异常,因为cobertura for 2.5.1的解析器与java语法不是最新的.
有人可以帮助我让这个适用于2.6.0版本以及更高版本的cobertura
解决方法
这与相关方向接壤,但可能提供帮助
这是由linux限制引起的,其中参数的大小不能超过128kb
请参阅Linux内核常量：MAX_ARG_STRLEN
https://github.com/torvalds/linux/blob/master/include/uapi/linux/binfmts.h
在Jenkins中,一旦您读取/超出了超出此值的变量,您将遇到此错误.
在我的例子中,我有一个github webhook,它启动了Jenkins作业并将有效负载参数设置为某个字符串>超过这个限制.尝试读取此参数会引发此错误.
为了解决这个问题,我有一个使用rest-api调用来读取父项值的子作业
您可以让父作业失败,但允许在所有情况下启动子作业.
下面是我用来提取信息的一个稍微改进的函数(为简洁而删除了错误检查和注释)
def get_parameter_value_from_parent():
host = 'https://[YOUR_COMPANY].ci.cloudbees.com'
this_build_url = os.environ.get('BUILD_URL')
request_auth = (JENKINS_USER,JENKINS_TOKEN)
url = '{0}/api/json'.format(this_build_url)
parameter_name = 'payload'
payload = ''
#
# Get the upstreamBuild number,and the upstreamUrl
# so we can put together a link to the upstream job
#
response = requests.get(url,auth=request_auth)
this_build = json.loads(response)
build_number = ''
short_url = ''
actions = this_build['actions']
for action in actions:
if action.get('causes'):
for cause in action.get('causes'):
build_number = cause['upstreamBuild']
short_url = cause['upstreamUrl']
parent_url = '{host}/{short_url}{build}/api/json'.format(host=host,short_url=short_url,build=build_number)
#
# Now get the payload from the parent job by making REST api call
#
response = requests.get(parent_url,auth=request_auth)
upstream_build = json.loads(response)
actions = upstream_build['actions']
for action in actions:
if action.get('parameters'):
for parameter in action.get('parameters'):
if parameter['name'] == parameter_name:
value = parameter['value']
payload = value
return payload
print 'Error: Unable to return payload from parent jenkins job: {0}'.format(parent_url)
sys.exit(1)
