Question

更新我尝试删除java openjdk的每一个痕迹，安装Oracle Java 8，再次设置我的环境变量，但仍然没有bueno。所以在我做完source ~/.bashrc之后，我关闭了所有终端，退出了，并且中提琴都被修复了。不过有点麻烦。

OP： 我遇到了SO question，这似乎与我遇到的问题有关。不幸的是，我的export JAVA_HOME=/usr/lib/jvm/default-java文件中没有usr/bin/gradle行。

我的错误是JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64/jre

但echo $JAVA_HOME会返回/usr/lib/jvm/java-8-openjdk-amd64/jre

我尝试在真正的JAVA_HOME之间创建一个符号链接，并且一个gradle继续尝试使用但是一个gradle试图使用的不是真的所以我得到了错误ln: failed to create symbolic link '/usr/lib/jvm/java-7-openjdk-amd64/jre': No such file or directory

我尝试挖掘gradlew文件并找到我认为可能违规的代码，但我不能100％确定它是如何工作的，任何时候我编辑文件然后执行cordova run android所有我的更改都是擦去。

这是我在gradlew中找到的一些代码：

# 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

Answer 1

首先，Java home应该看起来像/usr/lib/jvm/java-8-oracle，没有＆＃39; jre＆＃39;部分。其次，它应该放在/ etc / profile文件中：

export JAVA_HOME="/usr/lib/jvm/java-8-oracle"

export PATH=$JAVA_HOME/bin:$PATH

运行cordova android build时，Gradle使用了错误的JAVA_HOME
