How do I fix: the trustAnchors parameter must be non-empty?

Please help. I’ve been stuck with this and it’s not letting me move forward. I tried searching for the solution but nothing seems to work.
I get the following exception when trying to run ./gradlew:

Exception in thread "main" javax.net.ssl.SSLException: java.lang.RuntimeException: Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty at java.base/sun.security.ssl.Alerts.getSSLException(Alerts.java:214) at java.base/sun.security.ssl.SSLSocketImpl.fatal(SSLSocketImpl.java:1974) at java.base/sun.security.ssl.SSLSocketImpl.fatal(SSLSocketImpl.java:1926) at java.base/sun.security.ssl.SSLSocketImpl.handleException(SSLSocketImpl.java:1909) at java.base/sun.security.ssl.SSLSocketImpl.startHandshake(SSLSocketImpl.java:1436) at java.base/sun.security.ssl.SSLSocketImpl.startHandshake(SSLSocketImpl.java:1413) at java.base/sun.net.www.protocol.https.HttpsClient.afterConnect(HttpsClient.java:567) at java.base/sun.net.www.protocol.https.AbstractDelegateHttpsURLConnection.connect(AbstractDelegateHttpsURLConnection.java:185) at java.base/sun.net.www.protocol.http.HttpURLConnection.getInputStream0(HttpURLConnection.java:1581) at java.base/sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1509) at java.base/sun.net.www.protocol.https.HttpsURLConnectionImpl.getInputStream(HttpsURLConnectionImpl.java:245) at org.gradle.wrapper.Download.downloadInternal(Download.java:60) at org.gradle.wrapper.Download.download(Download.java:45) at org.gradle.wrapper.Install$1.call(Install.java:62) at org.gradle.wrapper.Install$1.call(Install.java:48) at org.gradle.wrapper.ExclusiveFileAccessManager.access(ExclusiveFileAccessManager.java:69) at org.gradle.wrapper.Install.createDist(Install.java:48) at org.gradle.wrapper.WrapperExecutor.execute(WrapperExecutor.java:107) at org.gradle.wrapper.GradleWrapperMain.main(GradleWrapperMain.java:61) Caused by: java.lang.RuntimeException: Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty at java.base/sun.security.validator.PKIXValidator.<init>(PKIXValidator.java:89) at java.base/sun.security.validator.Validator.getInstance(Validator.java:181) at java.base/sun.security.ssl.X509TrustManagerImpl.getValidator(X509TrustManagerImpl.java:330) at java.base/sun.security.ssl.X509TrustManagerImpl.checkTrustedInit(X509TrustManagerImpl.java:180) at java.base/sun.security.ssl.X509TrustManagerImpl.checkTrusted(X509TrustManagerImpl.java:192) at java.base/sun.security.ssl.X509TrustManagerImpl.checkServerTrusted(X509TrustManagerImpl.java:133) at java.base/sun.security.ssl.ClientHandshaker.checkServerCerts(ClientHandshaker.java:1947) at java.base/sun.security.ssl.ClientHandshaker.certificateStatus(ClientHandshaker.java:1798) at java.base/sun.security.ssl.ClientHandshaker.processMessage(ClientHandshaker.java:276) at java.base/sun.security.ssl.Handshaker.processLoop(Handshaker.java:1098) at java.base/sun.security.ssl.Handshaker.processRecord(Handshaker.java:1026) at java.base/sun.security.ssl.SSLSocketImpl.processInputRecord(SSLSocketImpl.java:1137) at java.base/sun.security.ssl.SSLSocketImpl.readRecord(SSLSocketImpl.java:1074) at java.base/sun.security.ssl.SSLSocketImpl.readRecord(SSLSocketImpl.java:973) at java.base/sun.security.ssl.SSLSocketImpl.performInitialHandshake(SSLSocketImpl.java:1402) at java.base/sun.security.ssl.SSLSocketImpl.startHandshake(SSLSocketImpl.java:1429) ... 14 more Caused by: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty at java.base/java.security.cert.PKIXParameters.setTrustAnchors(PKIXParameters.java:200) at java.base/java.security.cert.PKIXParameters.<init>(PKIXParameters.java:120) at java.base/java.security.cert.PKIXBuilderParameters.<init>(PKIXBuilderParameters.java:104) at java.base/sun.security.validator.PKIXValidator.<init>(PKIXValidator.java:86) ... 29 more
I have java version:

openjdk 10.0.1 2018-04-17
OpenJDK Runtime Environment (build 10.0.1+10-Ubuntu-3ubuntu1)
OpenJDK 64-Bit Server VM (build 10.0.1+10-Ubuntu-3ubuntu1, mixed mode)```

How do I fix this? I am using Ubuntu 18.04, 64bit

I had exactly the same problem, with the same jdk. It seems the problem doesn’t come from Gradle but from Open JDK itself.
I followed the answer given by k0pernikus on this thread :

and purged everything from java (openjdk but also java-common) to reinstall openjdk-8, and now it works without a problem.
