我在最新的Debian测试中使用以下配置:
$ bazel version
Bazelisk version: v1.10.1
Starting local Bazel server and connecting to it...
Build label: 4.0.0
Build target: bazel-out/k8-opt/bin/src/main/java/com/google/devtools/build/lib/bazel/BazelServer_deploy.jar

Build timestamp: 1611214404
Build timestamp as int: 1611214404
我已经安装了openjdk 11(目前是11.0.11)，update-alternatives通过/usr/bin/java指向它。环境变量JAVA_HOMEisunset.
在此配置中，以下命令失败:
$ bazel coverage --config=linux_x86 -c dbg --instrumentation_filter="//implementation:atos_utest" //implementation/src/utest:all 2>&1 | tee /tmp/buildlog.txt

其他构建命令成功。这是一个VM设置，在具有上述相同配置的其他VM实例上，此命令成功。
我很感激你的提示。像bazel clean这样简单的事情在类似的问题中没有帮助，我甚至完全删除了构建缓存，但无济于事。顺便说一句。我的构建与android无关。
我也有同样的错误，但我通过正确安装jdk解决了这个问题。检查您的bazel版本是否没有标记此警告:
bazel version
Bazelisk version: v1.11.0
**WARNING: Ignoring JAVA_HOME, because it must point to a JDK, not a JRE.**
Build label: 4.2.1
Build target: bazel-out/k8-opt/bin/src/main/java/com/google/devtools/build/lib/bazel/BazelServer_deploy.jar
Build time: Mon Aug 30 15:17:47 2021 (1630336667)
Build timestamp: 1630336667
Build timestamp as int: 1630336667
如果出现此警告，则意味着jdk有问题，请使用以下命令验证是否安装了javac命令:
javac -version
如果未安装，请查找您的平台的安装，在我的情况下，它使用以下命令:
sudo apt install default-jdk
最后用以下命令验证安装目录:
sudo update-alternatives --config javac
确保正确配置了JAVA_HOME。
今天，我长时间以来第一次重新测试，问题似乎消失了。
虚拟机运行bullseye。巴泽尔版本:
$ bazel version
Bazelisk version: v1.10.1
Build label: 4.2.1
Build target: bazel-out/k8-opt/bin/src/main/java/com/google/devtools/build/lib/bazel/BazelServer_deploy.jar

$ java --version
openjdk 11.0.13 2021-10-19
OpenJDK Runtime Environment (build 11.0.13+8-post-Debian-1deb11u1)
OpenJDK 64-Bit Server VM (build 11.0.13+8-post-Debian-1deb11u1, mixed mode, sharing)
也许是海森堡…
这是一个令人困惑的错误信息-它说它找不到bin/java，但我的系统上确实有java可用。
问题是我有JRE (Java运行时环境)，它允许您使用java命令运行Java程序，但我没有JDK (Java开发环境)，它允许您使用javac命令编译 Java代码。这才是巴泽尔真正想要的。
我在RHEL 8上，所以我像这样安装它:
sudo dnf install java-1.8.0-openjdk-devel
