解决Lombok与ButterKnife集成问题
本文介绍了一个在集成Lombok与ButterKnife时遇到的编译错误,并提供了详细的解决方案。错误提示要求明确声明注解处理器,通过在build.gradle文件中添加特定配置解决了该问题。

在集成lomBok butterknife时 用到注解build报如下错误

 Error:FAILURE: Build failed with an exception.

* What went wrong:
    Execution failed for task ':app:javaPreCompileDebug'.
            > Annotation processors must be explicitly declared now.  The following dependencies on the compile classpath are found to contain annotation processor.  Please add them to the annotationProcessor configuration.
    - lombok-1.16.18.jar (org.projectlombok:lombok:1.16.18)
    Alternatively, set android.defaultConfig.javaCompileOptions.annotationProcessorOptions.includeCompileClasspath = true to continue with previous behavior.  Note that this option is deprecated and will be removed in the future.
    See https://developer.android.com/r/tools/annotation-processor-error-message.html for more details.

            * Try:
    Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

解决:

在app的build中
android {
    ...
    defaultConfig {
        ...
        //添加如下配置就OK了
        javaCompileOptions { annotationProcessorOptions { includeCompileClasspath = true } }
    }
    ...
}

import androidx.annotation.Nullable; import androidx.appcompat.app.AppCompatActivity; import android.content.Intent; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.TextView; import android.widget.Toast; import com.google.zxing.integration.android.IntentIntegrator; import com.google.zxing.integration.android.IntentResult; public class MainActivity extends AppCompatActivity { private Button btnScan; private TextView tvResult; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); btnScan = findViewById(R.id.btnScan); tvResult = findViewById(R.id.tvResult); btnScan.setOnClickListener(v -> { // 初始化扫描器 IntentIntegrator integrator = new IntentIntegrator(this); integrator.setDesiredBarcodeFormats(IntentIntegrator.QR_CODE); // 只扫描二维码 integrator.setPrompt("将二维码放入扫描框内"); // 提示文字 integrator.setCameraId(0); // 使用后置摄像头 integrator.setBeepEnabled(true); // 扫描成功提示音 integrator.setOrientationLocked(false); // 允许旋转 integrator.initiateScan(); // 启动扫描 }); } // 接收扫描结果 @Override protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) { super.onActivityResult(requestCode, resultCode, data); IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data); if (result != null) { if (result.getContents() == null) { Toast.makeText(this, "扫描已取消", Toast.LENGTH_SHORT).show(); } else { // 显示扫描结果 tvResult.setText("扫描结果: " + result.getContents()); } } } } 提示Unused import statement如何解决
