-<!-- OAT(OSS Audit Tool) configuration guide:
-basedir: Root dir, the basedir + project path is the real source file location.
-licensefile: 
-1.If the project don't have "LICENSE" in root dir, please define all the license files in this project in , OAT will check license files according to this rule.
-
-tasklist(only for batch mode):
-1. task: Define oat check thread, each task will start a new thread.
-2. task name: Only an name, no practical effect.
-3. task policy: Default policy for projects under this task, this field is required and the specified policy must defined in policylist.
-4. task filter: Default filefilter for projects under this task, this field is required and the specified filefilter must defined in filefilterlist.
-5. task project: Projects to be checked, the path field define the source root dir of the project.
-
-
-policyList:
-1. policy: All policyitems will be merged to default OAT.xml rules, the name of policy doesn't affect OAT check process.
-2. policyitem: The fields type, name, path, desc is required, and the fields rule, group, filefilter is optional,the default value is:
-<policyitem type="" name="" path="" desc="" rule="may" group="defaultGroup" filefilter="defaultPolicyFilter"/>
-3. policyitem type:
-    "compatibility" is used to check license compatibility in the specified path; 
-    "license" is used to check source license header in the specified path;
-    "copyright" is used to check source copyright header in the specified path;
-    "import" is used to check source dependency in the specified path, such as import ... ,include ...
-    "filetype" is used to check file type in the specified path, supported file types: archive, binary
-    "filename" is used to check whether the specified file exists in the specified path(support projectroot in default OAT.xml), supported file names: LICENSE, README, README.OpenSource
