java.lang.NoClassDefFoundError：无法初始化类 org.apache.http.conn.ssl.SSLConnectionSocketFactory

Question

I am facing the following issue :

java.lang.NoClassDefFoundError: Could not initialize class org.apache.http.conn.ssl.SSLConnectionSocketFactory

I am using httpclient 4.5 jar. Could you please let me know how to resolve it?

SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslcontext, new String[] {"TLSv1" }, null,
                       SSLConnectionSocketFactory.BROWSER_COMPATIBLE_HOSTNAME_VERIFIER);

my pom.xml contains the following dependency -

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.5</version>
    <scope>provided</scope>
</dependency>

We had the same problem with java.lang.NoClassDefFoundError: Could not initialize class org.apache.http.conn.ssl.SSLConnectionSocketFactory and there was appropriate dependency in Maven.

The reason of the problem in our case was tika-app, when we changed it to tica-core the problem was solved. The part commented below we replaced with the part above:

    <dependency>
        <groupId>org.apache.tika</groupId>
        <artifactId>tika-core</artifactId>
        <version>1.19.1</version>
    </dependency>

    <!--<dependency>
        <groupId>org.apache.tika</groupId>
        <artifactId>tika-app</artifactId>
        <version>1.16</version>
    </dependency>-->
