如何使用外部jar文件為java創建makefile？

Question

我有一個java項目，需要編寫makefile讓它在Linux上運行。 我的項目包括外部jar文件和資源包（.txt資源）。我真的是Linux的新手，只是學習如何編寫makefile。

我引用一些材料並編寫一個這樣的makefile：

# Set the file name of your jar package:
JAR_PKG = ADBproject1.jar

# Set your entry point of your java app:
ENTRY_POINT = adb/Bing_WebResults/Run.java

# Need resource directory
RES_DIR = yes

SOURCE_FILES = \
adb/jsonModels/Metadata.java \
adb/jsonModels/Result.java \
adb/jsonModels/Data.java \
adb/jsonModels/DataContainer.java \
adb/models/Weight_ID.java \
adb/models/Pair.java \
adb/models/Document.java \
adb/models/Collections.java \
adb/Bing_WebResults/Bing_Search.java\
adb/Bing_WebResults/Run.java \


JAVAC = javac
JFLAGS = -encoding UTF-8


vpath %.class bin
vpath %.java src

# show help message by default
Default:
    @echo "make new: new project, create src, bin, res dirs."
    @echo "make build: build project."
    @echo "make clean: clear classes generated."
    @echo "make rebuild: rebuild project."
    @echo "make run: run your app."
    @echo "make jar: package your project into a executable jar."

build: $(SOURCE_FILES:.java=.class)

# pattern rule
%.class: %.java
    $(JAVAC) -cp bin -d bin $(JFLAGS) $<

rebuild: clean build

.PHONY: new clean run jar

new:
ifeq ($(RES_DIR),yes)
    mkdir -pv src bin res
else
    mkdir -pv src bin
endif

clean:
    rm -frv bin/*

run:
    java -cp bin $(ENTRY_POINT)

jar:
ifeq ($(RES_DIR),yes)
    jar cvfe $(JAR_PKG) $(ENTRY_POINT)  -C bin . res
else
    jar cvfe $(JAR_PKG) $(ENTRY_POINT) -C bin .
endif

但我不知道如何將這兩個外部.jar文件（gson.jar，commons.jar）添加到makefile中。 而且我不太確定我寫的文件路徑是否正確。

Answer 1

javac有一個-cp和-classpath參數：

-classpath <path>          Specify where to find user class files and
                           annotation processors
-cp <path>                 Specify where to find user class files and
                           annotation processors

就文檔而言，它們似乎是等價的。

Answer 2

我通過將所有* .jar文件添加到新文件夾“lib”來解決問題。 然后javac -sourcepath src/ -classpath lib/*.jar將解決外部jar文件問題。
