使用Maven时出现“jssecacerts PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilde”错

解决方法：
方法一：忽略SSL证书检查

在Maven命令后加入参数“-Dmaven.wagon.http.ssl.insecure=true -Dmaven.wagon.http.ssl.allowall=true”

方法二. 生成JDK证书并导入JRE security中

1. 生成JDK证书

import javax.net.ssl.*;
import java.io.*;
import java.security.KeyStore;
import java.security.MessageDigest;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;

public class InstallCert

public static void main(String[] args) throws Exception
String host;
int port;
char[] passphrase;
if ((args.length == 1) || (args.length == 2))
String[] c = args[0].split(":");
host = c[0];
port = (c.length == 1) ? 443 : Integer.parseInt(c[1]);
String p = (args.length == 1) ? "changeit" : args[1];
passphrase = p.toCharArray();
else
System.out

return;

file = new File(dir, "jssecacerts");
if (file.isFile() == false)
file = new File(dir, "cacerts");


System.out.println("Loading KeyStore " + file + "...");
InputStream in = new FileInputStream(file);
KeyStore ks = KeyStore.getInstance(KeyStore.getDefaultType());
ks.load(in, passphrase);
in.close();

SSLContext context = SSLContext.getInstance("TLS");
TrustManagerFactory tmf = TrustManagerFactory
.getInstance(TrustManagerFactory.getDefaultAlgorithm());
tmf.init(ks);
X509TrustManager defaultTrustManager = (X509TrustManager) tmf
.getTrustManagers()[0];
SavingTrustManager tm = new SavingTrustManager(defaultTrustManager);
context.init(null, new TrustManager[]tm, null);
SSLSocketFactory factory = context.getSocketFactory();

System.out
.println("Opening connection to " + host + ":" + port + "...");
SSLSocket socket = (SSLSocket) factory.createSocket(host, port);
socket.setSoTimeout(10000);
try
System.out.println("Starting SSL handshake...");
socket.startHandshake();
socket.close();
System.out.println();
System.out.println("No errors, certificate is already trusted");
catch (SSLException e)
System.out.println();
e.printStackTrace(System.out);

X509Certificate[] chain = tm.chain;
if (chain == null)
System.out.println("Could not obtain server certificate chain");
return;

System.in));

System.out.println();
System.out.println("Server sent " + chain.length + " certificate(s):");
System.out.println();
MessageDigest sha1 = MessageDigest.getInstance("SHA1");
MessageDigest md5 = MessageDigest.getInstance("MD5");
for (int i = 0; i < chain.length; i++)
X509Certificate cert = chain[i];
System.out.println(" " + (i + 1) + " Subject "
+ cert.getSubjectDN());
System.out.println(" Issuer " + cert.getIssuerDN());
sha1.update(cert.getEncoded());
System.out.println(" sha1 " + toHexString(sha1.digest()));
md5.update(cert.getEncoded());
System.out.println(" md5 " + toHexString(md5.digest()));
System.out.println();

System.out
.println("Enter certificate to add to trusted keystore or ‘q‘ to quit: [1]");
String line = reader.readLine().trim();
int k;
try
k = (line.length() == 0) ? 0 : Integer.parseInt(line) - 1;
catch (NumberFormatException e)
System.out.println("KeyStore not changed");
return;

X509Certificate cert = chain[k];
String alias = host + "-" + (k + 1);
ks.setCertificateEntry(alias, cert);

OutputStream out = new FileOutputStream("jssecacerts");
ks.store(out, passphrase);

System.out.println();
System.out.println(cert);

private static final char[] HEXDIGITS = "0123456789abcdef".toCharArray();

private static String toHexString(byte[] bytes)
StringBuilder sb = new StringBuilder(bytes.length * 3);
for (int b : bytes)
b &= 0xff;
sb.append(HEXDIGITS[b >> 4]);
sb.append(HEXDIGITS[b & 15]);
sb.append(‘ ‘);

return sb.toString();

private static class SavingTrustManager implements X509TrustManager

private final X509TrustManager tm;
private X509Certificate[] chain;

SavingTrustManager(X509TrustManager tm)
this.tm = tm;

public X509Certificate[] getAcceptedIssuers()
throw new UnsupportedOperationException();

public void checkClientTrusted(X509Certificate[] chain, String authType)
throws CertificateException
throw new UnsupportedOperationException();

public void checkServerTrusted(X509Certificate[] chain, String authType)
throws CertificateException
this.chain = chain;
tm.checkServerTrusted(chain, authType);

传入domain参数(如repo.maven.apache.org)后运行程序，后台交互过程中输入1，生成jssecacerts证书。
2. 将生成的证书导入JRE security库中

将生成的证书拷贝至$JAVA_HOME/jre/lib/security

3. 重启系统使设置生效

4. mvn命令加上参数-Djavax.net.ssl.trustStore=$JAVA_HOME/jre/lib/security/cacerts
