Question

我有一个makefile，它执行以下操作：

all:    
    CLASSPATH=$(SELF)/RT/real:$(SELF)/RT/fake:$(SELF)/RT/fake/uj javac $(SELF)/RT/real/java/lang/*.java
    CLASSPATH=$(SELF)/RT/real:$(SELF)/RT/fake:$(SELF)/RT/fake/uj javac $(DIR)/Components/UJ*.java 
    find $(SELF)/RT/real -iname "*.class" -type f >> $(SELF)/files
    find $(DIR)/Components -iname "UJCmp.class" -type f >> $(SELF)/files
    $(foreach C, $(shell echo $(CLASSES) | tr ',' ' '), \
        CLASSPATH=$(SELF)/RT/real:$(SELF)/RT/fake:$(SELF)/RT/fake/uj \
        javac $(DIR)/Components/UJ*.java $(DIR)/Components/$(C).java && \
        find $(DIR)/Components -iname "$(C).class" >> $(SELF)/files && \
    ) true
    cat $(SELF)/files | xargs $(CMD) >$(OUT)

但是在终端中产生以下输出：

奇怪的是，符号.Xlen_（）和其他符号包含在＆＃34; / home / sven / git / uJVM_PhD_Project / UPNP / uJ / BUILDENV / RT / fake / uj / lang中的.java文件中/MiniString.java" （并且是公开的）。因此，在尝试编译UJCmp.java时，我认为它包含在类路径中。所以我不知道它为什么会产生这个错误。

我错过了什么？

编辑：我有一个相当奇怪的设置并覆盖默认的String类。我也会在这里发布MiniString和String的源代码：

String.java位于＆＃34; /home/sven/git/uJVM_PhD_Project/UPNP/uJ/BUILDENV/RT/real/java/lang/String.java"和代码：

package java.lang;

import uj.lang。*;

public class String extends MiniString {

public String(byte[] bytes){    //our constructor for raw bytes
    super(bytes);
}

}

MiniString.java位于＆＃34; /home/sven/git/uJVM_PhD_Project/UPNP/uJ/BUILDENV/RT/fake/uj/lang/MiniString.java"和代码：

    package uj.lang;

public class MiniString{

    public static String Xnew_(byte[] bytes){
        return new String(bytes);
    }

    public byte XbyteAt_(int loc){
        return 0;
    }

    public int Xlen_(){ 
        return 0;
    }

    public MiniString(byte[] bytes){}

    public int length(){
        return 0;
    }

    public char charAt(int pos){
        return 0;   
    }
}

Java - ＆＃34;错误：找不到符号＆＃34;
