Question

失败：构建失败，并出现异常。

出了什么问题：任务'：app：kaptDebugKotlin'的执行失败。

执行org.jetbrains.kotlin.gradle.internal.KaptExecution时发生故障 java.lang.reflect.InvocationTargetException（无错误消息）

尝试：使用--info或--debug选项运行，以获取更多日志输出。使用--scan运行以获取完整的见解。
例外是： org.gradle.api.tasks.TaskExecutionException：任务'：app：kaptDebugKotlin'的执行失败。 ....... 造成原因：java.lang.NoClassDefFoundError：org / antlr / v4 / runtime / CharStreams ....

原因：java.lang.ClassNotFoundException：org.antlr.v4.runtime.CharStreams ...另外45个

build.gradle项目：

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

我添加了这个：

configurations.all() {
        resolutionStrategy.force "org.antlr:antlr4-runtime:4.5.3"
        resolutionStrategy.force "org.antlr:antlr4-tool:4.5.3"
}

因为如果我不明白，用于代码生成的“ ANTLR工具版本4.5.3与当前运行时版本4.7.1不匹配”，用于解析器编译的ANTLR运行时版本4.5.3与当前运行时版本4.7.1不匹配。 “例外

Answer 1

我有一些建议可以帮助一些人使用 Android Studio 和 Gradle 自动重新生成用于 Android 的 ANTLR4 代码。我的设置的完整工作示例位于 with my project here。

首先回答发帖人的部分问题。 org.antlr:antlr4-runtime:4.5.3 和 org.antlr:antlr4-tool:4.5.3 包似乎过时了。尽管许多较旧的帖子建议使用这些依赖项。我发现以下内容将包括最新版本的 ANTLR4（检查 ANTLR4 存储库以获取更新版本）：

dependencies {
    // ...
    implementation 'org.antlr:antlr4:4.9.1'
}

对于典型的 Android 应用程序，我们需要先应用以下股票插件：

apply plugin: 'com.android.application'

问题是这破坏了 Gradle 与 ANTLR4 插件的使用。解决方法是在您的 shell 路径中安装 antlr4 实用程序，然后在应用程序 build.gradle 配置中执行以下类似操作：

/* NOTE: The gradle plugin with Android does not work, this is a shell command within the standard system paths. */
def generateAntlrJava(String grammarFile) {
    def scriptRunCmd = "antlr -o app/src/main/antlr-gen -package 'com.my.package.name' -Dlanguage=Java" +
            " -listener -visitor -long-messages -lib 'path/to'" +
            " -Xexact-output-dir 'path/to" + grammarFile + "'";
    def cmdResult = ['bash', '-c', scriptRunCmd].execute();
    cmdResult.waitFor();
    return cmdResult.text
}

task PreBuildGenAntlr4JavaSources {
    println 'REMOVING OLD ANTLR4 JAVA SOURCES ==> '
    file(new File('app/src/main/antlr-gen')).deleteDir()
    println 'GENERATING ANTLR4 JAVA SOURCES ==> '
    file(new File('app/src/main/antlr-gen')).mkdirs()
    generateAntlrJava("MyScriptLexer.g4")
    generateAntlrJava("MyScriptParser.g4")
    outputs.upToDateWhen { false } /* Make the task run every time (no UP-TO-DATE skippage) */
}
preBuild.dependsOn PreBuildGenAntlr4JavaSources

task cleanPreBuildGenAntlr4JavaSources {
    println 'REMOVING OLD ANTLR4 JAVA SOURCES ==> '
    file(new File('app/src/main/antlr-gen')).deleteDir()
    println 'GENERATING ANTLR4 JAVA SOURCES ==> '
    file(new File('app/src/main/antlr-gen')).mkdirs()
    generateAntlrJava("MyScriptLexer.g4")
    generateAntlrJava("MyScriptParser.g4")
}
clean.dependsOn cleanPreBuildGenAntlr4JavaSources

就是这样。唯一适用于我的用例的解决方案 :)
