使用exthmui11的源码与lineage18.1的设备树进行编译，参照lineage wiki进行编译。运行mka target-files-package otatools成功生成target files，在使用sign_target_files_apks进行签名时遇到问题

首先使用build/tools/releasetools中的工具运行，出现如下结果

$ ./build/tools/releasetools/sign_target_files_apks -o -d ~/.android-certs     $OUT/obj/PACKAGING/target_files_intermediates/*-target_files-*.zip     signed-target_files.zip

提示找不到signapk.jar。
再使用out/host/linux-x86/bin中的工具进行，出现如下结果
