java.lang.IllegalArgumentException:由于密钥无效，无法初始化

我收到一个加密异常

我在跑步

• OSX10.11
• Java 1.8
• Groovy版本：2.4.4
• 梯度2.3-20141027185330+0000
• JAVA_HOME=/Library/JAVA/JavaVirtualMachines/jdk1.8.0_05.jdk/Contents/HOME

我将Oracle JCE策略JAR安装到$JAVA_HOME/lib/security目录中：

$ ls -l $JAVA_HOME/lib/security
total 16
-rw-r--r--@ 1 root  wheel  2487 Oct  9 17:21 US_export_policy.jar
-rw-r--r--@ 1 root  wheel  2500 Oct  9 17:21 local_policy.jar

例外情况如下：

}发生这种情况的其他原因：

• 您在项目中没有使用JDK而不是JRE
• 您没有将策略jar放在正确的文件夹中（基本上是JDK/jre/lib/security——请参阅自述文件）

---

此问题最常见的原因是/lib/security没有安装Java加密扩展（JCE）无限强度权限策略文件

---

按照ReadMe文件进行操作，您应该已经启动并运行了

这里有一个下载JCE 8的命令

curl -q -L -C - -b "oraclelicense=accept-securebackup-cookie" -o /tmp/jce_policy-8.zip \
   -O http://download.oracle.com/otn-pub/java/jce/8/jce_policy-8.zip && \
   unzip -oj -d /usr/lib/jvm/java-8-oracle/jre/lib/security \
   /tmp/jce_policy-8.zip \*/\*.jar \
   && rm /tmp/jce_policy-8.zip

---

这假设您在

/usr/lib/JVM/java-8-Oracle

有一个Oracle JVM 8，这可能是java JRE版本不匹配的问题

通过将JRE版本从

jdk1.8.0\u 111\JRE

升级到

jdk1.8.0\u 181\JRE

---

希望您不必有额外的库。

您可以将加密代码放在其他位置，我们如何判断您是否会出错？这些文件的大小对于Oracle JDK8 unlimited strength policy JAR来说并不正确，但是对于JDK7来说是正确的大小。确保你使用下载的8。你是对的！问题解决了！
