gradle build fails on lint task

Question

I have a simple android project that I created with Android Studio 0.4.0. I use Gradle 1.9 and Gradle Android Plugin 0.7. Yesterday I've added Jake Wharton's ButterKnife library in my gradle build script:

dependencies {
            compile 'com.android.support:support-v4:19.0.0'
            compile 'com.android.support:appcompat-v7:19.0.0'

            // Butterknife
            compile 'com.jakewharton:butterknife:4.0.1'
}

When I run the application from Android Studio, the build runs fine and executes correctly on my devices. But when I try (from the command line) gradle build the build fails. Here is a part from my lint report:

InvalidPackage: Package not included in Android

/home/yami/.gradle/caches/modules-2/files-2.1/com.jakewharton/butterknife/4.0.1/f43b36925363701633d01adb8e54df7150397a78/butterknife-4.0.1.jar: Invalid package reference in library; not included in Android: javax.annotation.processing. Referenced from butterknife.internal.InjectViewProcessor.

Maybe I'm missing something, but not to be able to build the project in the terminal blocks the possibility of CI for Android projects.

Any help would be great.

Answer 1

With 0.7.0 there comes extended support for Lint, however, it does not work always properly. (Eg. the butterknife library)

Solution is to disable aborting build on found lint errors

I took the inspiration from https://android.googlesource.com/platform/tools/base/+/e6a5b9c7c1bca4da402de442315b5ff1ada819c7

(implementation: https://android.googlesource.com/platform/tools/base/+/e6a5b9c7c1bca4da402de442315b5ff1ada819c7/build-system/gradle/src/main/groovy/com/android/build/gradle/internal/model/DefaultAndroidProject.java )

(discussion: https://plus.google.com/+AndroidDevelopers/posts/ersS6fMLxw1 )

android {
  // your build config
  defaultConfig { ... }
  signingConfigs { ... }
  compileOptions { ... }
  buildTypes { ... }
  // This is important, it will run lint checks but won't abort build
  lintOptions {
      abortOnError false
  }
}

---

And if you need to disable just particular Lint rule and keep the build failing on others, use this:

/*
 * Use only 'disable' or only 'enable', those configurations exclude each other
 */
android {
  lintOptions {
    // use this line to check all rules except those listed
    disable 'RuleToDisable', 'SecondRuleToDisable'
    // use this line to check just listed rules
    enable 'FirstRuleToCheck', 'LastRuleToCheck'
  }
}

Answer 2

if abortOnError false will not resolve your problem, you can try this.

lintOptions {
    checkReleaseBuilds false
}

Answer 3

You can select proper options from here

android {
    lintOptions {
        // set to true to turn off analysis progress reporting by lint
        quiet true
        // if true, stop the gradle build if errors are found
        abortOnError false
        // if true, only report errors
        ignoreWarnings true
        // if true, emit full/absolute paths to files with errors (true by default)
        //absolutePaths true
        // if true, check all issues, including those that are off by default
        checkAllWarnings true
        // if true, treat all warnings as errors
        warningsAsErrors true
        // turn off checking the given issue id's
        disable 'TypographyFractions','TypographyQuotes'
        // turn on the given issue id's
        enable 'RtlHardcoded','RtlCompat', 'RtlEnabled'
        // check *only* the given issue id's
        check 'NewApi', 'InlinedApi'
        // if true, don't include source code lines in the error output
        noLines true
        // if true, show all locations for an error, do not truncate lists, etc.
        showAll true
        // Fallback lint configuration (default severities, etc.)
        lintConfig file("default-lint.xml")
        // if true, generate a text report of issues (false by default)
        textReport true
        // location to write the output; can be a file or 'stdout'
        textOutput 'stdout'
        // if true, generate an XML report for use by for example Jenkins
        xmlReport false
        // file to write report to (if not specified, defaults to lint-results.xml)
        xmlOutput file("lint-report.xml")
        // if true, generate an HTML report (with issue explanations, sourcecode, etc)
        htmlReport true
        // optional path to report (default will be lint-results.html in the builddir)
        htmlOutput file("lint-report.html")

        // set to true to have all release builds run lint on issues with severity=fatal
        // and abort the build (controlled by abortOnError above) if fatal issues are found
        checkReleaseBuilds true
        // Set the severity of the given issues to fatal (which means they will be
        // checked during release builds (even if the lint target is not included)
        fatal 'NewApi', 'InlineApi'
        // Set the severity of the given issues to error
        error 'Wakelock', 'TextViewEdits'
        // Set the severity of the given issues to warning
        warning 'ResourceAsColor'
        // Set the severity of the given issues to ignore (same as disabling the check)
        ignore 'TypographyQuotes'
    }
}
