android - jack 服务器无法(重新)启动

Question

我正在尝试构建 Android N，但我不断收到此错误:

15:37:13 FAILED: /bin/bash -c "(prebuilts/sdk/tools/jack-admin install-server prebuilts/sdk/tools/jack-launcher.jar prebuilts/sdk/tools/jack-server-4.8.ALPHA.jar  2>&1 || (exit 0) ) && (JACK_SERVER_VM_ARGUMENTS=\"-Dfile.encoding=UTF-8 -XX:+TieredCompilation\" prebuilts/sdk/tools/jack-admin start-server 2>&1 || exit 0 ) && (prebuilts/sdk/tools/jack-admin update server prebuilts/sdk/tools/jack-server-4.8.ALPHA.jar 4.8.ALPHA 2>&1 || exit 0 ) && (prebuilts/sdk/tools/jack-admin update jack prebuilts/sdk/tools/jacks/jack-2.28.RELEASE.jar 2.28.RELEASE || exit 47; prebuilts/sdk/tools/jack-admin update jack prebuilts/sdk/tools/jacks/jack-3.36.CANDIDATE.jar 3.36.CANDIDATE || exit 47; prebuilts/sdk/tools/jack-admin update jack prebuilts/sdk/tools/jacks/jack-4.7.BETA.jar 4.7.BETA || exit 47 )"

我在 jack-admin 代码中放置了一些日志，当我执行 ./jack-admin start-server 时出现以下错误。

有人可以帮忙吗？

编辑

1. Jack 服务器日志干净，没有异常或错误。

2. 默认端口 8076 和 8077 被阻止，如 netstat -nlp 所示，这表明服务器确实已启动。

   tcp6 0 0 127.0.0.1:8076:::* 监听 19180/java
   tcp6 0 0 127.0.0.1:8077:::* 听 19180/java

3. 我正在构建代码的机器位于代理后面。

Answer 1

当我遇到 Curl 错误 7 时，它在运行 jack-diagnose 时伴随着 SSL 错误。以下解决方案对我有用:

1. 编辑 java.security /etc/java-8-openjdk/security/ 下的文件
2. 从 jdk.tls.disabledAlgorithms 中移除 TLSv1、TLSv1.1
3. 重启 jack 服务器:
   • cd <your-aosp-home-dir>/prebuilts/sdk/tools/
   • ./jack-admin kill-server
   • ./jack-admin start-server
