Java工程使用Maven或者gradle构建,在fabric 使用docker 构建Java智能合约,构建脚本:
bash
#!/usr/bin/env bash
set -ex
INPUT_DIR=/chaincode/input
OUTPUT_DIR=/chaincode/output
TMP_DIR=$(mktemp -d)
NUM_JARS=$(find ${INPUT_DIR} -name "*.jar" | wc -l)
buildGradle() {
echo "Copying from $1 to ${TMP_DIR}"
cd $1
tar cf - . | (cd ${TMP_DIR}; tar xf -)
cd ${TMP_DIR}
echo "Gradle build"
if [ -f ./gradlew ]; then
chmod +x ./gradlew
./gradlew build shadowJar -x test
else
/root/chaincode-java/gradlew build shadowJar -x test
fi
retval=$?
if [ $retval -ne 0 ]; then
exit $retval
fi
cp build/libs/chaincode.jar $2
retval=$?
if [ $retval -ne 0 ]; then
exit $retval
fi
touch $2/.uberjar
cd "$SAVED" >/dev/null
}
buildMaven() {
echo "Copying from $1 to ${TMP_DIR}"
cd $1
tar cf - . | (cd ${TMP_DIR}; tar xf -)
cd ${TMP_DIR}
echo "Maven build"
if [ -f ./mvnw ]; then
chmod +x ./mvnw
else
cp -r /root/chaincode-java/.mvn .
cp /root/chaincode-java/mvnw .
fi
./mvnw compile package -DskipTests -Dmaven.test.skip=true
retval=$?
if [ $retval -ne 0 ]; then
exit $retval
fi
cp target/chaincode.jar $2
retval=$?
if [ $retval -ne 0 ]; then
exit $retval
fi
touch $2/.uberjar
cd "$SAVED" >/dev/null
}
for DIR in ${INPUT_DIR} ${INPUT_DIR}/src; do
if [ -f ${DIR}/build.gradle -o -f ${DIR}/build.gradle.kts ]; then
buildGradle ${DIR} ${OUTPUT_DIR}
exit 0
elif [ -f ${DIR}/pom.xml ]; then
buildMaven ${DIR} ${OUTPUT_DIR}
exit 0
fi
done
if [ ${NUM_JARS} -eq 0 ]; then
>&2 echo "Not build.gradle nor pom.xml found in chaincode source, don't know how to build chaincode"
>&2 echo "Project folder content:"
>&2 find ${INPUT_DIR} -name "*" -exec ls -ld '{}' \;
exit 255
else
cd ${INPUT_DIR} && tar cf - $(find . -name "*.jar") | (cd ${OUTPUT_DIR} && tar xvf -)
fi
从build.sh看出支持gradle、maven、jar三种方式。
maven构建慢的原因
bash
$ docker ps -a

.mvnw 打包使用.mvn目录,.mvn包含maven-wrapper.properties文件。
bash
# ll .mvn/wrapper/

-rw-rw-r-- 1 root root 218 May 23 18:11 maven-wrapper.properties
maven-wrapper.properties:
bash
cat .mvn/wrapper/maven-wrapper.properties

wrapperUrl=https://repo.maven.apache.org/maven2/io/takari/maven-wrapper/0.5.6/maven-wrapper-0.5.6.jar
maven是通过Apache网站下载,总所周知,国内下载apache数据比较慢的,maven构建工程慢(或者超时)的原因只是在此。
使用Jar安装合约
工程目录结构如下:
bash
$ ll
total 56
drwxrwxr-x 6 along along 4096 Aug 20 20:14 ./

1. maven 打包
bash
$ ./mvnw compile package -DskipTests -Dmaven.test.skip=true
打包完成后:
bash
$ tree target/

chaincode.jar是我们需要的合约jar。
2. 构建打包目录
bash
# 新建src目录
$ mkdir src
#拷贝chaincode.jar 到src目录
cp fabric_warehouse_supplies/target/chaincode.jar src/
$ tree src/
src/
└── chaincode.jar
3. peer package(打包链码)
bash
$ peer lifecycle chaincode package warehouse_supplies_v1.tar.gz --path /home/along/go/src/github.com/Hyperledger/fabric-java/src/ --lang java --label warehouse_supplies_v1
/home/along/go/src/github.com/Hyperledger/fabric-java/src/
是存放chaincode.jar的目录。
查看打包的信息
bash
# 解压
$ mkdir chaincode && tar -txvf warehouse_supplies_v1.tar.gz -C chaincode
$ ll chaincode/

$ tar -zxvf code.tar.gz
# 解压后的src
$ tree

4. peer install(安装链码)
安装链码
bash
