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 )"

15:37:13 No Jack server running. Try 'jack-admin start-server'
15:37:13 No Jack server running. Try 'jack-admin start-server'

我在代码中放入了一些日志jack-admin，当我这样做时，我收到以下错误./jack-admin start-server。

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，如图所示，netstat -nlp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 :::* 监听 19180/java

3. 我正在构建代码的机器位于代理后面。

Answer 1

当我收到 Curl 错误 7 时，运行 jack-diagnose 时还伴随着 SSL 错误。以下解决方案对我有用：

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