安装 java 链码抛出无效内存地址错误

Question

我将 1.4.0-rc2 用于 docker 图像和 java 代码。

当尝试使用以下命令将 java 链代码从 cli 安装到对等点时：

peer chaincode install -p github.com/hyperledger/chaincode/java/ -l java -n java_chaincode -v 0

抛出以下错误：

在该文件夹中是一个按照教程创建的 jar，即 on github。

编辑 1：

上面的错误是因为路径不正确，我使用的是相对于 gopath 的路径，因为我之前必须为 go 链代码这样做，但使用完整路径进行安装。

对于实例化：

peer chaincode instantiate -n chaincode -v 0 -C channel -c '{"Args":["init"]}' -l java

给出以下错误：

Error: could not assemble transaction, err proposal response was not successful, error code 500, msg error starting container: error starting container: Failed to generate platform-specific docker build: Error returned from build: 127 "/bin/sh: 1: ./build.sh: not found
"

这是同行的日志：

我很乐意提供更多信息和代码。

直接从 jar 安装链代码并不是那么简单，您需要为此更改脚本或从 jar 文件创建自定义映像，我花了几个小时才弄清楚这一点。对于，

对等链码安装和对等链码实例化

源代码是“必要的”，因为 peer 执行“docker pull”来下载特定于 java 的镜像，以便在内部构建它并启动链码容器。您可以执行 docker exec 来检查chaincode.jar 是在chaincode 容器内创建的。

现在来到您的错误运行时错误：无效的内存地址或 nil 指针取消引用，您能否检查路径是否正确，并共享对等日志，我很乐意提供帮助。
