Here is an example of lint warnings produced by this check:

local.properties:11:Error: Windows file separators (\) and drive letter
separators (':') must be escaped (\\) in property files; use
C\:\\my\\path\\to\\sdk [PropertyEscape]
windows.dir=C:\my\path\to\sdk
             --------------
local.properties:14:Error: Windows file separators (\) and drive letter
separators (':') must be escaped (\\) in property files; use
C\:\\Documents and Settings\\UserName\\Local Settings\\Application
Data\\Android\\android-studio\\sdk [PropertyEscape]
ok.sdk.dir=C:\\Documents and Settings\\UserName\\Local Settings\\Application Data\\Android\\android-studio\\sdk
            -

Here is the source file referenced above:

local.properties:

# This file should *NOT* be checked into Version Control Systems,

sdk.dir=/Users/test/dev/sdks
windows.dir=C:\my\path\to\sdk
windows2.dir=C\:\\my\\path\\to\\sdk
not.a.path.prop=Hello \my\path\to\sdk
ok.sdk.dir=C:\\Documents and Settings\\UserName\\Local Settings\\Application Data\\Android\\android-studio\\sdk

You can also visit the source code for the unit tests for this check to see additional scenarios.

The above example was automatically extracted from the first unit test found for this lint check, PropertyFileDetector.testBasic. To report a problem with this extracted sample, visit https://issuetracker.google.com/issues/new?component=192708.

You can suppress false positives using one of the following mechanisms:

• Using a suppression comment like this on the line above:

  #noinspection PropertyEscape
  key = problematic-value

• Using a special lint.xml file in the source tree which turns off the check in that folder and any sub folder. A simple file might look like this:

  <?xml version="1.0" encoding="UTF-8"?>
  <lint>
      <issue id="PropertyEscape" severity="ignore" />
  </lint>

  Instead of ignore you can also change the severity here, for example from error to warning. You can find additional documentation on how to filter issues by path, regular expression and so on here.

• In Gradle projects, using the DSL syntax to configure lint. For example, you can use something like

  lintOptions {
      disable 'PropertyEscape'
  }

  In Android projects this should be nested inside an android { } block.

• For manual invocations of lint, using the --ignore flag:

  $ lint --ignore PropertyEscape ...`

• Last, but not least, using baselines, as discussed here.
