Unresolved dependency and Server access error, InvalidAlgorithmParameterException

[shawnw19]

The problem I met happened in Maven resolution, which is similar to #32 .

For %maven org.knowm.xchart:xchart:3.5.2, the error is:

---------------------------------------------------------------------------
java.lang.RuntimeException: Exception occurred while running line magic 'maven': Error resolving 'org.knowm.xchart:xchart:3.5.2'. [unresolved dependency: org.knowm.xchart#xchart;3.5.2: not found, unresolved dependency: org.knowm.xchart#xchart;3.5.2: not found]
	at io.github.spencerpark.ijava.runtime.Magics.lineMagic(Magics.java:19)
	at .(#19:1)

And for %maven org.apache.commons:commons-math3:3.6.1 , the error is:

:: problems summary ::

	Server access error at url https://repo.maven.apache.org/maven2/org/apache/commons/commons-math3/3.6.1/commons-math3-3.6.1.pom (javax.net.ssl.SSLException: java.lang.RuntimeException: Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty)

The second type of error also happens in things like

%%loadFromPOM
<dependency>
    <groupId>org.deeplearning4j</groupId>
    <artifactId>deeplearning4j-core</artifactId>
    <version>1.0.0-beta4</version>
</dependency>

I tried some solutions in stackoverflow targeted for same exception and errors (like this ) but failed.

For your information, the Jupyter was installed separately without Anaconda. The version of Java is 10.

Thank you very much in advance for your help.

this is because the repository cannot be visited. so I think you should update your repository or change another repository
