日誌在哪裏申報？

我試圖提出一個補丁deeplearning4j，但首先我需要能夠建立該項目。我可以使用手動指令從maven構建它，但IntelliJ（2016.3.6）發現錯誤，並且當我查看源代碼時，我不會責怪它。日誌在哪裏申報？

我特別難過的源文件是https://github.com/deeplearning4j/deeplearning4j/blob/master/deeplearning4j-nlp-parent/deeplearning4j-nlp/src/main/java/org/deeplearning4j/models/word2vec/StaticWord2Vec.java，它有一對變量log的夫婦引用，它沒有在此文件中聲明。

package org.deeplearning4j.models.word2vec; 

import lombok.extern.slf4j.Slf4j; 
import org.deeplearning4j.models.embeddings.WeightLookupTable; 
import org.deeplearning4j.models.embeddings.reader.ModelUtils; 
import org.deeplearning4j.models.embeddings.wordvectors.WordVectors; 
import org.deeplearning4j.models.word2vec.wordstore.VocabCache; 
import org.nd4j.linalg.api.ndarray.INDArray; 
import org.nd4j.linalg.compression.AbstractStorage; 
import org.nd4j.linalg.factory.Nd4j; 
import org.nd4j.linalg.ops.transforms.Transforms; 

import java.util.ArrayList; 
import java.util.Collection; 
import java.util.List; 
import java.util.Map; 
import java.util.concurrent.ConcurrentHashMap; 

/** 
* This is special limited Word2Vec implementation, suited for serving as lookup table in concurrent multi-gpu environment 
* This implementation DOES NOT load all vectors onto any of gpus, instead of that it holds vectors in, optionally, compressed state in host memory. 
* This implementation DOES NOT provide some of original Word2Vec methods, such as wordsNearest or wordsNearestSum.

@Slf4j 
public class StaticWord2Vec implements WordVectors { 
    private List<Map<Integer, INDArray>> cacheWrtDevice = new ArrayList<>(); 
    private AbstractStorage<Integer> storage; 
    private long cachePerDevice = 0L; 
    private VocabCache<VocabWord> vocabCache; 
    private String unk = null; 
... snipped

該類擴展了接口，但沒有明確擴展父類。檢查使用javap的Maven的生成的類文件，我看到：

Compiled from "StaticWord2Vec.java" 
public class org.deeplearning4j.models.word2vec.StaticWord2Vec 
implements org.deeplearning4j.models.embeddings.wordvectors.WordVectors { 
private static final org.slf4j.Logger log; 
... snipped

對於所有未來的問題，在Gitter for DL4J上都有一個非常活躍的開發社區：https://gitter.im/deearningarning4j/deeplearning4j – tremstat

看一看'@ Slf4j'註釋 - https://projectlombok.org/ api/lombok/extern/slf4j/Slf4j.html –

我終於注意到了註釋@Slf4j和跟蹤import語句，發現我需要的Lombok plugin增加的IntelliJ是能夠建立這個項目。
