我需要将我的SSL证书文件添加到JVM信任存储中。我已经安装了java oracle 8和java adoptium 17。
在link之后，我成功地为java 8添加了证书，并且可以使用该证书进行通信。

keytool -importcert -alias startssl -keystore $JAVA_HOME/jre/lib/security/cacerts -storepass changeit -file ca.crt

但是现在我也需要把这个添加到java 17中，用同样的命令，我无法添加证书，我发现java 17的JAVA_HOME没有目录jre/lib/security，而是有conf/security目录，所以我把命令改为

keytool -importcert -alias startssl -keystore $JAVA_HOME/conf/security/cacerts -storepass changeit -file ca.crt

这个命令在security文件夹下生成了cacerts文件，但是我还是收到了错误。在添加证书之前，我在java 8中收到了同样的错误。我应该把这个java 17的cacerts文件放在哪里？
