Question

我以前在Cloud Foundry中成功部署了一个java应用程序。但是，现在开发人员已经添加了一个从C编译的共享库。我已将.so添加到.zip文件中（我使用通用打包程序并通过zip文件部署到Cloud Foundry）和确保.so可执行。但是，当我部署时，我收到一个错误：

2016-12-23T14:39:01.013+00:00 [STG/0] [OUT] -----> Java Buildpack Version: eba4df6 | git://github.com/cloudfoundry/java-buildpack.git#eba4df6

所以我的理解是我需要从Java Buildpack创建一个Custom Buildpack。但是，我在这一点上遇到了代码： https://github.com/ONSdigital/java-buildpack/blob/master/bin/compile#L28

# Adding crf tagger library
status "Adding crf tagger support"
cp $bp_dir/parsers/src/main/resources/libbackend.so $build_dir/vendor/

# update the PATH
status "Building runtime environment"
mkdir -p $build_dir/.profile.d
echo "export PATH=\"$HOME/bin:\$HOME/vendor/:\$PATH\";" > $build_dir/.profile.d/crftagger.sh
echo "export LD_LIBRARY_PATH=\"\$HOME/vendor/\";" >> $build_dir/.profile.d/crftagger.sh

根据我的收集，我只需要修改compile阶段。我需要做什么才能复制.so并使Buildpack成功运行。

请查看此https://docs.cloudfoundry.org/devguide/deploy-apps/deploy-app.html#profile

预运行时挂钩你需要的。我不能给你更多的细节，因为你没有提供足够的信息（项目结构，你在你的根目录中有.profile等）。

如果您需要添加共享库，请尝试使用attr_reader :additional_libraries https://github.com/cloudfoundry/java-buildpack/blob/master/docs/extending-droplet.md

如何在Cloud Foundry中将自定义C共享库与Java应用程序捆绑在一起？
