反推法
根据 “ 14.95 MB/15.52 MB downloaded “，我们在ResourceOperation 中找到了满足我们看到的这种格式。

// type 
public enum Type{
        download,
        upload;

        public String getCapitalized() {
            return StringUtils.capitalize(toString());
        }
    }
// 类型
private final Type operationType;

// 格式  14.95 MB/15.52 MB downloaded 多像呀
String.format("%s/%s %sed", //第一个%s为14.95 MB，第二个%s为15.52 MB，第三个%s为download
              getLengthText(totalProcessedBytes), 
              contentLengthString, 
              operationType) // Type.download

public class ResourceOperation {
    public enum Type{
        download,
        upload;

        public String getCapitalized() {
            return StringUtils.capitalize(toString());
        }
    }
    private final ProgressLogger progressLogger;
    private final Type operationType;
    private final String contentLengthString;
    private final String resourceName;

    private long loggedKBytes;
    private long totalProcessedBytes;

    public ResourceOperation(ProgressLogger progressLogger, Type type, long contentLength, String resourceName) {
        this.progressLogger = progressLogger;
        this.operationType = type;
        this.contentLengthString = getLengthText(contentLength != 0 ? contentLength : null);
        this.resourceName = resourceName;
    }

    private String getLengthText(Long bytes) {
        if (bytes == null) {
            return "unknown size";
        }
        if (bytes < 1024) {
            return bytes + " B";
        } else if (bytes < 1048576) {
            return (bytes / 1024) + " KB";
        } else {
            return String.format("%.2f MB", bytes / 1048576.0);
        }
    }

    public void logProcessedBytes(long processedBytes) {
        totalProcessedBytes += processedBytes;
        long processedKB = totalProcessedBytes / 1024;
        if (processedKB > loggedKBytes) {
            loggedKBytes = processedKB;
            String progressMessage = String.format("%s/%s %sed", getLengthText(totalProcessedBytes), contentLengthString, operationType);
            progressLogger.progress(progressMessage);
        }
    }

    public void completed() {
        this.progressLogger.completed();
    }
}

找到之后就很简单了，我们给build.gradle添加一个新的依赖或者删除一个aar的依赖，并且在 寻找调用 logProcessedBytes的地方，设置断点。
这里我们删除一个androidx.activity:activity:1.2.3的依赖

DefaultBuildOperationExecutor 下载时创建线程池 线程池名（Build operations）

在调用getArtifact的地方都会触发下载检查，如果没有下载才会触发下载
