bash - Ubuntu AndroidStudio颤动：未设置JAVA_HOME

Question

我在 android studio 中运行我的颤振应用程序时遇到问题。

它给了我以下信息

Launching lib/main.dart on sdk gphone x86 in debug mode...
Running Gradle task 'assembleDebug'...

ERROR: JAVA_HOME is not set and no 'java' command could be found in your PATH.

Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.

Exception: Gradle task assembleDebug failed with exit code 1

这是echo $JAVA_HOME，我已将 bin 添加到我的 PATH

/usr/lib/jvm/openjdk-14.0.2_linux-x64_bin/jdk-14.0.2

flutter run在将 gradle 从升级gradle-5.6.2-all.zip到之后，我可以从终端运行颤振gradle-6.3-all.zip

我认为问题在于以下脚本中的 android/gradlew

# Determine the Java command to use to start the JVM.
if [ -n "$JAVA_HOME" ] ; then
    if [ -x "$JAVA_HOME/jre/sh/java" ] ; then
        # IBM's JDK on AIX uses strange locations for the executables
        JAVACMD="$JAVA_HOME/jre/sh/java"
    else
        JAVACMD="$JAVA_HOME/bin/java"
    fi
    if [ ! -x "$JAVACMD" ] ; then
        die "ERROR: JAVA_HOME is set to an invalid directory: $JAVA_HOME

Please set the JAVA_HOME variable in your environment to match the
location of your Java installation."
    fi
else
    JAVACMD="java"
    which java >/dev/null 2>&1 || die "ERROR: JAVA_HOME is not set and no 'java' command could be found in your PATH.

Please set the JAVA_HOME variable in your environment to match the
location of your Java installation."
fi

我尝试复制并运行它，它运行没有问题，#!/usr/bin/env bash哪个是 gradlew 中的 shebang

我尝试重新安装android studio，但没有成功。我flutter doctor --verbose的是一团糟。起初它找不到android studio-说它没有安装。所以我跑了flutter config --android-studio-dir="/snap/bin"，但现在我得到了这个输出，即使我安装了插件

谢谢大家，希望我错过了一些简单的东西！
