我试图扩展OpenTelemetry java代理，我没有看到任何迹象表明它试图加载我的jar。我正在运行以下cmd：

java -javaagent:../src/main/resources/opentelemetry-javaagent.jar -Dotel.javaagent.configuration-file=../src/main/resources/agent-prp.properties -jar simple-service-1.0-SNAPSHOT-jar-with-dependencies.jar

字符串
我的配置文件是（属性工作）：

otel.javaagent.extensions=/Users/foo/source/simple-service/src/main/resources/span-processor-1.0-SNAPSHOT.jar
otel.resource.attributes=service.name=foooBarr

型
我的分机是：

import com.fasterxml.jackson.databind.ObjectMapper;
import io.opentelemetry.context.Context;

public class FooSpanProcessor implements SpanProcessor {

    private static final Logger log = LoggerFactory.getLogger(FooSpanProcessor.class);

    @Override
    public void onStart(Context parentContext, ReadWriteSpan span) {
        log.error("fffffffffff");
        span.setAttribute("fooToken", FooProperties.INSTANCE.fooToken);

        span.setAttribute("envs", FooProperties.INSTANCE.environment);
        span.setAttribute("metaData", FooProperties.INSTANCE.metadata);
    }

    @Override
    public boolean isStartRequired() {
        return true;
    }

    @Override
    public void onEnd(ReadableSpan span) {
    }
    ....

我没有看到任何迹象表明我的扩展已加载，我没有看到任何我的参数上产生的跨度。任何机构可以帮助我吗？
