我正在尝试按照他们的说明运行 lenskit-hello。当我运行
./gradlew build
时,我收到错误

我在 MacOS Mojave 10.14.6 上使用 Java 1.8.0_241(并且仅安装了该版本)。我已经安装了最新的安全更新,然后重新启动了计算机。我已经在我的常规 WiFi 和手机热点上尝试过此操作。
我按照接受的答案here中的说明进行操作,从
https://repo1.maven.org/maven2/org/lenskit/lenskit-all/3.0-M2/lenskit-all-3.0-M2.pom
和https://oss.sonatype.org/content/repositories/snapshots/org/lenskit/lenskit-all/3.0-M2/lenskit-all-3.0-M2.pom
下载安全证书,并通过以下命令将它们添加到密钥库(仅显示两个命令之一):
keytool -import -alias maven -file /Users/briennakh/Downloads/maven.cer -keystore
/Library/Java/JavaVirtualMachines/jdk1.8.0_241.jdk/Contents/Home/jre/lib/security/cacerts
然后如果我检查
keytool -list -keystore /Library/Java/JavaVirtualMachines/jdk1.8.0_241.jdk/Contents/Home/jre/lib/security/cacerts | grep maven
它显示我的证书已添加,
maven, Mar 17, 2020, trustedCertEntry
,但运行时仍然遇到相同的错误./gradlew build
?
我还检查了
openssl x509 -in /Users/briennakh/Downloads/maven.pem -text
以确保证书看起来没问题。
该 SSL 证书 本来就不是自签名的,因此不需要手动添加。尝试重新安装 Java 或将备用安装位置设置为
$JAVA_HOME
,并使用默认的 cacerts
文件。有些东西似乎被破坏了,因为它不应该拒绝 repo1.maven.org
的证书。 ls -la $JAVA_HOME/jre/lib/security/cacerts
表示 cacerts
应该有大约 114757 字节。如果您位于防火墙后面,您可能需要为 Gradle 配置代理。
这应该尝试 SSL 会话(不通过 Java):
$ openssl s_client -connect repo1.maven.org:443
这个项目还使用了 Gradle 的过时版本,例如:
distributionUrl=https\://services.gradle.org/distributions/gradle-5.6.4-all.zip
在网站上找到了这个方法(https://discuss.gradle.org/t/unable-to-build-a-java-project-due-to-certificates/46993)它解决了我的问题,没有附加任何内容java 证书和其他操作。但也许这并不安全!
